Pre-Calculus/Algebra Help Please!
!!! I needed some help on homework within which are problems my teacher had never explained how to do if anyone can help I would greatly appreciate it here they are:
Use the given zero to find the remaining zero of the given function:
f(x)=x^4-9x^3+21x^2+21x-130; zero: 3-2i
I was never told how to do long division including an i term
Write a polynomial that meets the given conditions: fourth degree polynomial with real coefficients; zeros -2, 0, 3+5i
Form a polynomial with the given information:
Degree 5; zeros:5, 6+5i, -5i
Again thank you for a response in advance
