Exercise
$2x^3+3x^2-23x-12$
Step-by-step Solution
Learn how to solve integrals of rational functions problems step by step online. Factor the expression 2x^3+3x^2-23x+-12. We can factor the polynomial 2x^3+3x^2-23x-12 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 -12. Next, list all divisors of the leading coefficient a_n, which equals 2. The possible roots \pm\frac{p}{q} of the polynomial 2x^3+3x^2-23x-12 will then be. Trying all possible roots, we found that 3 is a root of the polynomial. When we evaluate it in the polynomial, it gives us 0 as a result.
