Question

Which of the following is one of the factors of x2 + 4x - 32?

Answer 1

Well, I don't know what the choices are, but anyway, you just have to find two numbers that add up to 4 and multiply to get -32. Like -4 and 8. So we can stick those in the factoring.
\[(x-4)(x+8)\]
If you're lazy and hate factoring, you can also get your factors via the quadratic formula.

Answer 2

omg im so dumb thank you i forgot what factoring was!
