Simplifying a Ratio of Factored Polynomials

Simplifying a ratio of factored polynomials is an essential skill in algebra and geometry. It involves reducing complex expressions to their simplest form, making it easier to solve equations and inequalities. In this review, we will focus on simplifying the expression $\frac{54(w-4)(2w-5)}{6(2w-5)(w+6)}$ .

Understanding the Concept of Simplifying a Ratio of Factored Polynomials

Simplifying a ratio of factored polynomials involves canceling out common factors in the numerator and denominator. This is done by identifying the greatest common factor (GCF) of the two expressions and canceling it out. The GCF is the largest expression that divides both the numerator and denominator without leaving a remainder.

Steps to Simplify a Ratio of Factored Polynomials

To simplify a ratio of factored polynomials, follow these steps:

Identify the GCF: The first step is to identify the GCF of the numerator and denominator. This involves factoring both expressions and identifying the common factors.
Cancel out the GCF: Once the GCF is identified, cancel it out from both the numerator and denominator.
Simplify the expression: After canceling out the GCF, simplify the expression by multiplying the remaining factors.
