Chapter 7: Q. 70 (page 653)

For the following exercises, find $R (x) = \frac{f (x)}{g (x)}$ where $f (x) and g (x)$ are given.
role="math" localid="1644859186657" $f (x) = \frac{24 x^{2}}{2 x - 4} g (x) = \frac{12 x^{2} + 36 x}{x^{2} - 11 x + 18}$

Short Answer

Expert verified

The required result is $\frac{x (x - 9)}{(x + 3)}$ .

Step by step solution

Step 1. Given Information

The given rational expressions are $f (x) = \frac{24 x^{2}}{2 x - 4} g (x) = \frac{12 x^{2} + 36 x}{x^{2} - 11 x + 18}$

Step 2. Rewrite the Expression as a Product

Substitute the given values into $R (x) = \frac{f (x)}{g (x)}$ .
$R (x) = \frac{\frac{24 x^{2}}{2 x - 4}}{\frac{12 x^{2} + 36 x}{x^{2} - 11 x + 18}}$
Write the obtained expression as the product of numerator and the reciprocal of denominator.
$R (x) = \frac{24 x^{2}}{2 x - 4} 脳 \frac{x^{2} - 11 x + 18}{12 x^{2} + 36 x}$

Step 3. Factor the Numerator and Denomiantor

Express the numerator and denominator of the obtained expression as factors.

$R (x) = \frac{12 脳 2 脳 x 脳 x}{2 (x - 2)} 脳 \frac{(x - 2) (x - 9)}{12 脳 x 脳 (x + 3)}$

Step 4. Cancel out the Common Factors

Simplify the obtained expression by canceling out the common factors.

$\begin{array}{rcl} R (x) & = & \frac{12 脳 2 脳 x 脳 x}{2 (x - 2)} 脳 \frac{(x - 2) (x - 9)}{12 脳 x 脳 (x + 3)} \\ = & \frac{x (x - 9)}{(x + 3)} \end{array}$

So, the simplified values of $R (x)$ is $\frac{x (x - 9)}{(x + 3)}$ .
