Chapter 11: Q13. (page 731)

Simplify each expression.
$\frac{\frac{y^{2} + 10 y + 24}{y^{2} - 9}}{\frac{3 y^{2} + 17 y - 6}{2 y^{2} - 11 y + 15}}$

Short Answer

Expert verified

$\frac{(y + 4) (2 y - 5)}{(y + 3) (3 y - 1)}$

Step by step solution

Step 1. Division expression.

Write as a division expression.

$\frac{y^{2} + 10 y + 24}{y^{2} - 9} \div \frac{3 y^{2} + 17 y - 6}{2 y^{2} - 11 y + 15}$

Step 2. Divide.

To divide, multiply by the reciprocal.

$\frac{y^{2} + 10 y + 24}{y^{2} - 9} \cdot \frac{2 y^{2} - 11 y + 15}{3 y^{2} + 17 y - 6}$

Step 3. Factor.

Factor the given expression and simplify.

$\frac{(y + 4) (y + 6)}{(y + 3) (y - 3)} \cdot \frac{(2 y - 5) (y - 3)}{(y + 6) (3 y - 1)} = \frac{(y + 4) (2 y - 5)}{(y + 3) (3 y - 1)}$

Therefore, $\frac{\frac{y^{2} + 10 y + 24}{y^{2} - 9}}{\frac{3 y^{2} + 17 y - 6}{2 y^{2} - 11 y + 15}}$ can be simplified as $\frac{(y + 4) (2 y - 5)}{(y + 3) (3 y - 1)}$ .
