Question

Solve by factoring : x^2-5x-36=0
Part III: The sum of your two factors must be -5. Which of your factor pairs
above could produce this sum? (2 points)

Answer 1

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:

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

Answer 2

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