Question 141387: FIND THE ZEROS OF THE POLYNOMIAL FUNCTION AND STATE THE MULTIPLICITY IF EACH.
f(x)=x cubed+7x squared-x-7
A)-7, multiplicity 1; -1 multiplicity 2
B)-7, multiplicity 2; 1, multiplicity 1
C)-1 multiplicity 1; 1, multiplicity 1; 7, multiplicity 1
D)-7, multiplicity 1; -1 multiplicity 1; 1, multiplicity 1
I'm thinking the answer is D, but I would like to know for sure. Thanks!

Factor by grouping:

Zeros are at x=-7,x=1, and x=-1, each of multiplicity 1. D is correct!
