$\int\frac{n^4-5n^3+4n-48}{n+2}dn$
Learn how to solve problems step by step online. Integrate the function (n^4-5n^34n+-48)/(n+2). Find the integral. We can factor the polynomial n^4-5n^3+4n-48 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 -48. Next, list all divisors of the leading coefficient a_n, which equals 1. The possible roots \pm\frac{p}{q} of the polynomial n^4-5n^3+4n-48 will then be.
