Chapter 0.3, Problem 20E

To determine

To evaluate: the factors of polynomial.

Answer to Problem 20E

The factor of polynomial $4c^2-9$ is $\left(2c+3\right)\left(2c-3\right)$ .

Explanation of Solution

Given information :

Polynomial is given as $4c^2-9$

Factorizing the given polynomial,

  $\begin{array}{c}4c^2-9={\left(2c\right)}^2-3^2\\ {\left(2c\right)}^2-3^2=\left(2c+3\right)\left(2c-3\right)\end{array}$

So,

After factorizing $\left(2c+3\right)\left(2c-3\right)$ .
