2) Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to Heinz the other key features of g(x).

g(x) = x3 – x2 – 4x + 4( I chose this one)
g(x) = x3 + 2x2 – 9x – 18
g(x) = x3 – 3x2 – 4x + 12
g(x) = x3 + 2x2 – 25x – 50
g(x) = 2x3 + 14x2 – 2x – 14

I relly need help finding the zeros

anonymous · Answer

If you divide the last one by two, the following is the result:$$x^3+7 x^2-x-7 $$I couldn't factor this thing with pencil and paper if my life depended on it.
Mathemaitca says that (x-1) (x+1) (x+7) are the roots.
Is this one easier for you than the other polynomials?
