Question

Four polynomial functions are shown below:

\(f(x) = x^3 + 3x^2 - 4x - 12\)
\(g(x) = x^3 - 3x - 2\)
\(p(x) = x^2 + 3x + 2\)
\(t(x) = x^2 + x - 2\)

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

Answer 1

I'm thinking either C or D

Answer 2

not sure how to factor the first 2 but p(x) factors to (x+2)(x+1)

Answer 3

Its not the last one

Answer 4

\(p(x) = x^2 + 3x + 2\)
\(x^2 + 3x + 2=0\)
\((x+2)(x+1)=0\)
x={-1,-2}

Answer 5

Oh, thanks lol

Answer 6

np np :)
