f(x)=x(squared)-5x-24

I got f(x)=(x+3)(x-8) but is there any more to the problem?

Factor it, as Ace High did:

(x +3)(x - 8)

Set = 0:

(x + 3)(x - 8) = 0

Set each factor = 0:

x + 3 = 0 x - 8 = 0

solve each resulting equation individually

x + 3 = 0 --> x = -3
x - 8 = 0 --> x = 8

Your zeros are -3 and 8
