Find all zeros of the polynomial

P(x)=x^3-x-6

1 answer

First break down the polynomial. I ended up with (x-2)(x^2+2x+3).

Set x-2=0
Solve for x.

(x^2+2x+3)will not break down as easily into rational numbers. In this case you will have to use the quadratic formula.This problem you will give you imaginary numbers.
