Factor completely. x2-5x-36 Enter your answer in the box.

x^2 - 5x - 36 = (x - 9) (x + 4)

Step-by-step explanation:

You need to find two numbers whose product is - 36 and whose sum is - 5.

-36 = - 4 * 9; sum - 4 + 9 = 4 wrong sum

-36 = - 9 * 4; sum - 9 + 4 = - 5 right sum

The numbers are - 9 and 4.

Answer: x^2 - 5x - 36 = (x - 9) (x + 4)

(x - 9) (x + 4)

Step-by-step explanation:

x^2-5x-36

As you know, - 36 = - 9 * 4 and (-9) + 4 = - 5

so Factor

= (x - 9) (x + 4)
