Answer
$$x^3+3x^2-10x=0 $$
Work Step by Step
To write a cubic equation with the given values as solutions, we find the corresponding factors. We then FOIL out the factors to find the original quadratic equation:
$$ 0=-\left(x+5\right)\left(x\right)\left(x-2\right) \\ 0=\left(x\right)\left(x^2+3x-10\right)
\\ 0=x^3+3x^2-10x $$
