Answer 1

What degree polynomials have at least four roots?

Answer 2

What are all the real and complex roots of the polynomial 2x3 + 18x2 + 46x + 30

Answer 3

You can start by trying to graph or plot it to see how many roots it has. To find them you need to solve for y=0. In this case this polynomial nicely factors.
