Question

Solve by factoring : x^2-5x-36=0

Answer 1

The correct answer is x= 9 and -4 :) hope this helps

Answer 2

Answer:

-9 and +4 are the factors

Step-by-step explanation:

-9 times +4 is -36 and if you add +4 to -9, you get -5.

After this your function will look like this:

$x^2-9x+4x-36$

and then:

$x(x-9)+4(x-9)$

so the answer is:

$(x-9)(x+4)$
