Answer 2

Factor x^2 - 5x - 36 = 0

Answer 3

If factoring is an obstacle, go to wolframalpha.com

Enter x^2 - 5x - 36 = 0 in the question rectangle.

Scroll down and look at the answers.

Answer 4

Post what you get for checking.

Answer 5

x= 9, -4

Answer 6

(x-9)(x+4)=0

Answer 7

do you agree?

Answer 8

Yes. By solution, I assume you are to enter just 9 and -4.

Those answer regions look large for just answers.

Are you supposed to show work?

Answer 9

I think 9 goes in one response box and -4 in the other, the way that reads.

Answer 10

No, but I'm wondering if using the quadratic formula will get the same results?

Answer 11

I agree.

Answer 12

Yes. Use the Zero Product Property:

(x-9)(x+4)=0
x - 9 = 0 or x + 4 = 0
x = 9 or x = -4

This problem can be solved by factoring.
You can also use the Quadratic Formula.

Same two answers.

Answer 13

I agree.
\[\frac{ 5+\sqrt{169} }{ 2 }=9\]

Answer 14

\[\frac{ 5-\sqrt{169} }{ 2 }=-4\]

Answer 15

Looks good.
