Question

What are the factors of x^2-8x-20

Answer 1

(x+2)(x−10)

Explanation:

x^2-8x-20

Factoring means something like this:

(x+_)(x+_)

Add together to get -8

Multiply together to get -20

think of the two numbers

Try 2 and -10:

2+-10 = -8

2*-10 = -20

Fill in the blanks of with 2 and -10 to get

(x+_)(x+_) = (x+2)(x−10)

I hope it's right!
