Chapter 8: Q 34. (page 918)

In the following exercises, simplify.
$\frac{x^{2} + 4 x - 5}{x^{2} - 2 x + 1}$

Short Answer

Expert verified

The result is $\frac{x + 5}{x - 1}$ .

Step by step solution

Step 1. Given information.

Consider the given rational expression.

$\frac{x^{2} + 4 x - 5}{x^{2} - 2 x + 1}$

Step 2. Calculation.

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

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