# What is the factorization of x^2+2x-15?

May 17, 2018

$\left(x + 5\right) \left(x - 3\right)$

#### Explanation:

You want to get an equation ${x}^{2} + 2 x - 15$

The sum of numbers 2 and multiplication of numbers -15

(such as +5 and -2):

$\left(x + 5\right) \left(x - 3\right)$

$= {x}^{2} + 5 x - 3 x - 15$

$= {x}^{2} + 2 x - 15$

Your answer is $\left(x + 5\right) \left(x - 3\right)$
