When we encounter the expression "2 square root of 12," it means taking the square root of 12 and then multiplying the result by 2. This involves understanding the properties of square roots, such as the fact that every positive real number has two square roots: one positive and one negative.

Understanding square roots is crucial in various mathematical fields, including algebra, geometry, and calculus. It forms the foundation for solving equations, manipulating expressions, and understanding geometric shapes.

To understand the expression \(2 \sqrt{12}\), we need to break it down into simpler parts and comprehend the mathematical operations involved. Here is a step-by-step explanation:

1. Understanding the Square Root: The square root of a number is a value that, when multiplied by itself, gives the original number. For instance, the square root of 9 is 3 because \(3 \times 3 = 9\).

2. Expressing 12 in Terms of Its Prime Factors: We start by expressing 12 as a product of its prime factors:

   \(12 = 2 \times 2 \times 3\) or \(12 = 2^2 \times 3\).

3. Applying the Square Root to the Factors: We can take the square root of each factor separately:

   \(\sqrt{12} = \sqrt{2^2 \times 3}\).

4. Using the Property of Square Roots: According to the property \(\sqrt{a \times b} = \sqrt{a} \times \sqrt{b}\), we can simplify:

Here is the breakdown in a more visual format:

By following these steps, we can confidently simplify the expression \(2 \sqrt{12}\) to \(4 \sqrt{3}\).

To understand the expression \( 2 \sqrt{12} \), we first need to simplify \( \sqrt{12} \) using the prime factorization method. Here is a step-by-step breakdown:

1. Factorize 12 into Prime Factors:

   Prime factorization of 12 is \( 12 = 2 \times 2 \times 3 \). This can be written as:

   \[
   12 = 2^2 \times 3
   \]

2. Apply the Square Root to the Factors:

   To find \( \sqrt{12} \), we take the square root of each prime factor:

   \[
   \sqrt{12} = \sqrt{2^2 \times 3}
   \]

3. Simplify the Expression:

   The square root of \( 2^2 \) is 2, so we can simplify \( \sqrt{12} \) as follows:

   \[

   \]

4. Multiply by the Coefficient:

   Now, we return to the original expression \( 2 \sqrt{12} \) and substitute the simplified form of \( \sqrt{12} \):

   \[
   2 \sqrt{12} = 2 \times 2 \sqrt{3} = 4 \sqrt{3}
   \]

Simplifying square roots involves expressing the square root in its simplest form. This is done by factoring the number under the square root into its prime factors and then simplifying the expression by extracting squares from under the root. Let's take the square root of 12 as an example.

Here are the steps to simplify \(\sqrt{12}\):

1. Prime Factorization: Find the prime factors of 12.
   • 12 = 2 × 2 × 3
2. Group the prime factors into pairs:
   • 12 = (2 × 2) × 3
3. Take the square root of each pair:
   • \(\sqrt{12} = \sqrt{(2 \times 2) \times 3}\)
   • \(\sqrt{12} = \sqrt{2^2 \times 3}\)
4. Simplify by taking out the square factor:
   • \(\sqrt{2^2 \times 3} = 2 \sqrt{3}\)

Therefore, the simplified form of \(\sqrt{12}\) is \(2\sqrt{3}\).

Now, let's incorporate the coefficient 2 in front of the square root of 12:

1. We have the expression 2 \(\sqrt{12}\)
2. Substitute the simplified form of \(\sqrt{12}\):
   • 2 \(\sqrt{12} = 2 \times 2 \sqrt{3}\)
3. Combine the coefficients:
   • 2 \(\times 2 \sqrt{3} = 4 \sqrt{3}\)

Thus, the simplified form of the expression 2 \(\sqrt{12}\) is \(4\sqrt{3}\).

Using these steps, you can simplify any square root by breaking down the number into its prime factors and simplifying the expression.

To simplify the expression \(2 \sqrt{12}\), we can follow a step-by-step process:

1. Identify the prime factors of the number inside the square root.

   The number inside the square root is 12. We can find its prime factors:

   \(12 = 2 \times 2 \times 3\)

2. Group the prime factors into pairs.

   Since we have \(2 \times 2\), we can pair these factors:

   \(12 = 4 \times 3\)

3. Take the square root of each pair.

   The square root of 4 is 2. We can now rewrite the expression as:

   \(\sqrt{12} = \sqrt{4 \times 3} = \sqrt{4} \times \sqrt{3} = 2 \sqrt{3}\)

4. Multiply the result by the coefficient outside the square root.

   We started with \(2 \sqrt{12}\). Now we can substitute the simplified form of \(\sqrt{12}\):

   \(2 \sqrt{12} = 2 \times 2 \sqrt{3} = 4 \sqrt{3}\)

Thus, the simplified form of \(2 \sqrt{12}\) is \(4 \sqrt{3}\).

Combining like terms is a fundamental technique in algebra that simplifies expressions, making them easier to work with. Like terms are terms that have the same variable raised to the same power. When combining these terms, you simply add or subtract their coefficients.

When dealing with square roots or radicals, the process is similar, but you combine only those terms that have the same radicand (the number under the square root). Here's how you can combine like terms involving radicals:

1. Identify like terms: Ensure that the terms you want to combine have the same radical part. For example, \(2\sqrt{3}\) and \(5\sqrt{3}\) can be combined, but \(2\sqrt{3}\) and \(3\sqrt{5}\) cannot.
2. Add or subtract coefficients: Combine the coefficients of the like terms while keeping the radical part the same. For example:
   • \(2\sqrt{3} + 5\sqrt{3} = (2 + 5)\sqrt{3} = 7\sqrt{3}\)
   • \(7\sqrt{2} - 3\sqrt{2} = (7 - 3)\sqrt{2} = 4\sqrt{2}\)

Let's look at a detailed example to understand this process:

Consider the expression:

\(3\sqrt{8} + 2\sqrt{2}\)

1. Simplify each term:
   • \(3\sqrt{8} = 3\sqrt{4 \times 2} = 3 \times 2\sqrt{2} = 6\sqrt{2}\)
2. Rewrite the expression:

   \(6\sqrt{2} + 2\sqrt{2}\)

3. Combine like terms:
   • \(6\sqrt{2} + 2\sqrt{2} = (6 + 2)\sqrt{2} = 8\sqrt{2}\)

Thus, the simplified expression is \(8\sqrt{2}\).

Here is another example:

Combine \(4\sqrt{5} - 3\sqrt{5} + 2\sqrt{3}\):

1. Identify like terms:
   • \(4\sqrt{5}\) and \(-3\sqrt{5}\) are like terms.
   • \(2\sqrt{3}\) is not a like term with the others.
2. Combine like terms:
   • \(4\sqrt{5} - 3\sqrt{5} = (4 - 3)\sqrt{5} = 1\sqrt{5} = \sqrt{5}\)
3. Rewrite the expression:

   \(\sqrt{5} + 2\sqrt{3}\)

The final simplified form of the expression is \(\sqrt{5} + 2\sqrt{3}\).

Remember, combining like terms helps in simplifying expressions and solving equations more efficiently. Practice identifying and combining like terms to improve your algebraic skills!

When working with square roots, especially in expressions like \(2 \sqrt{12}\), it's important to be aware of common mistakes to avoid errors in simplification and calculation. Here are some frequent errors and tips on how to avoid them:

• Incorrectly Adding Square Roots:
  • Mistake: \( \sqrt{a} + \sqrt{b} = \sqrt{a+b} \)
  • Correction: \( \sqrt{a} + \sqrt{b} \neq \sqrt{a+b} \). For example, \( \sqrt{4} + \sqrt{9} \neq \sqrt{4+9} \). Instead, \( \sqrt{4} + \sqrt{9} = 2 + 3 = 5 \).
• Forgetting to Simplify Under the Radical:
  • Mistake: \( \sqrt{12} \) remains \( \sqrt{12} \)
  • Correction: Simplify \( \sqrt{12} = \sqrt{4 \times 3} = 2\sqrt{3} \). Thus, \( 2 \sqrt{12} = 2 \times 2\sqrt{3} = 4\sqrt{3} \).
• Misapplying the Distributive Property:
  • Mistake: \( 3\sqrt{3} + 3 = 6\sqrt{3} \)
  • Correction: \( 3\sqrt{3} + 3 = 3(\sqrt{3} + 1) \), not \( 6\sqrt{3} \).
• Incorrect Squaring of Square Roots:
  • Mistake: \( (\sqrt{a} + \sqrt{b})^2 = a + b \)
  • Correction: \( (\sqrt{a} + \sqrt{b})^2 = a + b + 2\sqrt{ab} \). For example, \( (\sqrt{2} + \sqrt{3})^2 = 2 + 3 + 2\sqrt{6} \).
• Misunderstanding the Difference Between Addition and Multiplication:
  • Mistake: \( 2\sqrt{3} \times 2\sqrt{3} = 4\sqrt{3} \)
  • Correction: \( 2\sqrt{3} \times 2\sqrt{3} = 4 \times 3 = 12 \).

By being aware of these common pitfalls and practicing correctly, you can improve your accuracy in simplifying and working with square roots.
