Introduction

Simplifying expressions involving square roots is a crucial skill in mathematics, particularly in algebra and geometry. It requires a deep understanding of the properties of square roots and the ability to manipulate expressions to their simplest form. In this article, we will simplify the given expression: $ -3 \sqrt{63} + 2 \sqrt{24} + 4 \sqrt{112} - \sqrt{3} $. We will break down the expression into smaller parts, simplify each part, and then combine them to obtain the final simplified expression.

Breaking Down the Expression

The given expression consists of four terms, each involving a square root. To simplify the expression, we need to simplify each term separately.

Term 1: $ -3 \sqrt{63} $

The first term involves the square root of 63. To simplify this term, we need to find the prime factorization of 63.

Prime Factorization of 63

63 can be factored as: $ 63 = 3^2 \times 7 $

Now, we can rewrite the first term as:

$ -3 \sqrt{63} = -3 \sqrt{3^2 \times 7} $

Using the property of square roots, we can rewrite this as:

$ -3 \sqrt{63} = -3 \times 3 \sqrt{7} $

Simplifying further, we get:

$ -3 \sqrt{63} = -9 \sqrt{7} $

Term 2: $ 2 \sqrt{24} $

The second term involves the square root of 24. To simplify this term, we need to find the prime factorization of 24.

Prime Factorization of 24

24 can be factored as: $ 24 = 2^3 \times 3 $

Now, we can rewrite the second term as:

$ 2 \sqrt{24} = 2 \sqrt{2^3 \times 3} $

Using the property of square roots, we can rewrite this as:

$ 2 \sqrt{24} = 2 \times 2 \sqrt{3} $

Simplifying further, we get:

$ 2 \sqrt{24} = 4 \sqrt{3} $

Term 3: $ 4 \sqrt{112} $

The third term involves the square root of 112. To simplify this term, we need to find the prime factorization of 112.

Prime Factorization of 112

112 can be factored as: $ 112 = 2^4 \times 7 $

Now, we can rewrite the third term as:

$ 4 \sqrt{112} = 4 \sqrt{2^4 \times 7} $

Using the property of square roots, we can rewrite this as:

$ 4 \sqrt{112} = 4 \times 2 \sqrt{7} $

Simplifying further, we get:

$ 4 \sqrt{112} = 8 \sqrt{7} $

Term 4: $ - \sqrt{3} $

The fourth term involves the square root of 3. This term is already simplified.

Combining the Terms

Now that we have simplified each term, we can combine them to obtain the final simplified expression.

$ -3 \sqrt{63} + 2 \sqrt{24} + 4 \sqrt{112} - \sqrt{3} $

Substituting the simplified values of each term, we get:

$ -9 \sqrt{7} + 4 \sqrt{3} + 8 \sqrt{7} - \sqrt{3} $

Combining like terms, we get:

$ -9 \sqrt{7} + 8 \sqrt{7} + 4 \sqrt{3} - \sqrt{3} $

Simplifying further, we get:

$ - \sqrt{7} + 3 \sqrt{3} $

Therefore, the simplified expression is:

$ - \sqrt{7} + 3 \sqrt{3} $
