Question

A20) Given that f(x) is a cubic function with zeros at −2−2 and 2i−2, find an equation for f(x) given that f(−7)=−6

B19) Find a degree 3 polynomial whose coefficient of x^3 equal to 1. The zeros of this polynomial are 5, −5i, and 5i. Simplify your answer so that it has only real numbers as coefficients.

C21) Find all of the zeros of P(x)=x^5+2x^3+xand list them below with zeros repeated according to their multiplicity.
Note: Enter the zeros as a list of complex numbers, where each zero is repeated according to its multiplicity, such as 5, 5, 3-4i, 5+i.
