Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int((x-1)/(x^2-16))dx. Expand the fraction \frac{x-1}{x^2-16} into 2 simpler fractions with common denominator x^2-16. Expand the integral \int\left(\frac{x}{x^2-16}+\frac{-1}{x^2-16}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int\frac{x}{x^2-16}dx results in: \frac{1}{2}\ln\left(x+4\right)+\frac{1}{2}\ln\left(x-4\right). Gather the results of all integrals.

Final answer to the problem

$\frac{1}{2}\ln\left|x-4\right|+\frac{1}{2}\ln\left|x+4\right|-\frac{1}{8}\ln\left|x-4\right|+\frac{1}{8}\ln\left|x+4\right|+C_0$
