Answer
$5x^2 - 25x$
Work Step by Step
Let's simplify the first fraction. When we do that, we get
$\frac{5}{x^{2} + 2x -3}$
Now, if we use the factoring method for the denominator, we get
$\frac{5}{(x+3)(x-1)}$
So now, this is what we have
$\frac{5}{(x+3)(x-1)} = \frac{?}{x(x-1)(x-5)(x+3)}$
Now multiply both sides by $(x+3)(x-1)$
$\frac{5}{1} = \frac{?}{x(x-5)}$
Now, let's cross multiply
$5x(x-5) =?$
$? = 5x^2 - 25x$
