what is a polynomial function in standard form with zeroes 1,2,3, and -3?
A. x^4-3x^3+7x^2-27x-18
B. x^4+3x^3-7x^2-27x-18
C. x^4-3x^3-7x^2+27x-18
D. x^4+3x^3+7x^2-27x-18
The answer is C. Expand each one of those zeros into its factorization form: x = 1 is (x - 1), x = 2 is (x - 2), etc. then FOIL the whole mess out. If you have 4 zeros you will have a 4th degree polynomial in the end.
