Four polynomial functions are shown below:

f(x) = x3 + 3x2 - 4x - 12
g(x) = x2 - x - 2
p(x) = x3 + 3x + 2
t(x) = x2 + x - 2

Which of the following functions has -1 and 2 as its zeros?

f(x)
g(x)
p(x)
t(x)

Any guesses on the answer or how to solve this problem yourself?

anonymous · Answer

im completely clueless here....The lessons are very brief and I dont know what to do

anonymous · Answer

Okay :) but do you mean x^2 and 3x^2 by X2 and 3X2

anonymous · Answer

Yes, sorry

anonymous · Answer

you're fine :) Okay, now if I can remember correctly, you want to try to put either -1 or 2 in for x

anonymous · Answer

okay, so do I just substitute them into the equations and see if it equals zero?

anonymous · Answer

yeah

anonymous · Answer

It cant be A becuase if it is -1 it equals negative 6

anonymous · Answer

I got B

anonymous · Answer

yay! :) good job
