13-51.

Identify all of the roots of the polynomial $p\left(x\right) = x^{3} + 4x^{2} + 6x + 4$.

Graphing the polynomial reveals that $x = −2$ is a root.
Divide out the corresponding factor $\left(x + 2\right)$.
Then use the Quadratic Formula to solve for the roots related to the resulting polynomial.
