Chapter 8: Q 35. (page 918)

In the following exercises, simplify.
$\frac{y^{2} + 3 y - 4}{y^{2} - 6 y + 5}$

Short Answer

Expert verified

The result is $\frac{y + 4}{y - 5}$ .

Step by step solution

Step 1. Given information.

Consider the given rational expression.

$\frac{y^{2} + 3 y - 4}{y^{2} - 6 y + 5}$

Step 2. Calculation.

Factor the numerator and denominator and remove the common factor from the numerator and the denominator.

$\begin{array}{l} \frac{y^{2} + 3 y - 4}{y^{2} - 6 y + 5} = \frac{y^{2} + 4 y - y - 4}{y^{2} - 5 y - y + 5} \\ = \frac{y (y + 4) - 1 (y + 4)}{y (y - 5) - 1 (y - 5)} \\ = \frac{(y + 4) (y - 1)}{(y - 5) (y - 1)} \\ = \frac{y + 4}{y - 5} \end{array}$
