Need the answer to this

ki77a [65]

Answer:

$\frac{2}{(x + 3)}$

Step-by-step explanation:

$\frac{2x - 10}{x^{2} - 2x - 15}$

pull 2 from top

$\frac{2(x - 5)}{x^{2} - 2x - 15}$

we are looking to cancel (x-5) so will start with

(x - 5)(x + 3), selected (x+3) because the sign must be negative and must multiply to -15

$\frac{2(x - 5)}{(x - 5)(x + 3)}$

now cancel (x-5)

$\frac{2}{(x + 3)}$
