Question

What are the zeros of the polynomial function: f(x) = x3 + x2 - 20x ?

Answer 1

Well, for one, you can set the equation to 0. Then you'll need to factor. There's something quite nice you can factor out. Do you know what it is?

Answer 2

5 and -4 :P

Answer 3

so -5 and 4? lol ty

Answer 4

Wait, wait, wait...you're not quite done. What you factored was x^2 + x - 20...but that's not quite the equation.

Answer 5

(although your two answers are right! There's one more though.)

Answer 6

yes i know lol i guess i just had a brain fart haha ty
