Learn how to solve common monomial factor problems step by step online. Factor the expression 15y^3-20y^2-20y. We can factor the polynomial 15y^3-20y^2-20y using the rational root theorem, which guarantees that for a polynomial of the form a_nx^n+a_{n-1}x^{n-1}+\dots+a_0 there is a rational root of the form \pm\frac{p}{q}, where p belongs to the divisors of the constant term a_0, and q belongs to the divisors of the leading coefficient a_n. List all divisors p of the constant term a_0, which equals 0. Next, list all divisors of the leading coefficient a_n, which equals 15. The possible roots \pm\frac{p}{q} of the polynomial 15y^3-20y^2-20y will then be. We can factor the polynomial 15y^3-20y^2-20y using synthetic division (Ruffini's rule). We found that 2 is a root of the polynomial.
