Question 76992: 2x^3+3x^2-2x=?
I know that I need to factor, but when it comes to cubes, I get confused.

In this case we have a common factor of x, so we can factor out an x


Now we can factor the quadratic in the parenthesis
ERROR Algebra::Solver::Engine::invoke_solver_noengine: solver not defined for name 'quadratic_factoring'.
Error occurred executing solver 'quadratic_factoring' .


So the quadratic in the parenthesis factors to this:

Now our factored polynomial looks like this


Notice if we foil the terms and distribute the x we get again
