-Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1 and the given zeros.

-3, -4 + i, 1-√3

Factor Polynomial completely

8c^3 - 512

Evaluate Expression

(1.5 x 10^4)(3.2 x 10^-8) <power of negative 8

(1.2 x 10^-7) <power of negative 7

-I could really use help on how to solve these. I have a test tomorrow and these are the main type of problems i didnt understand.
