Learn how to solve addition of numbers problems step by step online. Factor the expression 3x^3+x^2+2. We can factor the polynomial 3x^3+x^2+2 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 2. Next, list all divisors of the leading coefficient a_n, which equals 3. The possible roots \pm\frac{p}{q} of the polynomial 3x^3+x^2+2 will then be. Trying all possible roots, we found that -1 is a root of the polynomial. When we evaluate it in the polynomial, it gives us 0 as a result.
