Basic functions: Polynomial functions
Zeros of third degree polynomial functions
We consider the cubic polynomial \[P(x)=x^3+2\,x^2-x-2\] When we substitute \(x=1\), it turns out that \(P(1)=0\).
Find the other two zeros of the polynomial \(P(x)\).
Enter the answer in the form \(x=a\vee x=b\).
| Zeros of \(P(x)\) besides \(x=1\) are: |
