Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it is essential to understand the rules and techniques involved in simplifying expressions. In this article, we will focus on simplifying the given expression $\frac{8c^2 - 12d^2}{4}$ using various algebraic techniques.

Understanding the Expression

The given expression is a fraction, where the numerator is $8c^2 - 12d^2$ and the denominator is $4$ . To simplify this expression, we need to understand the rules of algebraic simplification. The expression can be simplified by factoring the numerator and then canceling out any common factors between the numerator and the denominator.

Factoring the Numerator

The numerator of the expression is $8c^2 - 12d^2$ . We can factor out the greatest common factor (GCF) of the two terms, which is $4$ . Factoring out the GCF, we get:

8c^2 - 12d^2 = 4(2c^2 - 3d^2)

Simplifying the Expression

Now that we have factored the numerator, we can simplify the expression by canceling out any common factors between the numerator and the denominator. In this case, the denominator is $4$ , which is also a factor of the numerator. Therefore, we can cancel out the common factor of $4$ between the numerator and the denominator:

\frac{8c^2 - 12d^2}{4} = \frac{4(2c^2 - 3d^2)}{4}

Canceling Out Common Factors

Now that we have canceled out the common factor of $4$ between the numerator and the denominator, we are left with:

\frac{4(2c^2 - 3d^2)}{4} = 2c^2 - 3d^2
