Am a newbie with additional math. When factorising polynomials with a constant of zero using the remainder theorem, the only method I can think of at the moment is random hit and miss since we have two unknown factors (for a cubic).
Please advise how, for a polynomial such as $f(x)= x^3-x^2-2x$, I should go about finding the other two factors (not x), as efficiently as possible?
Many thanks.

Once you factor out $\,x\,$ you are left with a quadratic. $\endgroup$
