Learn how to solve integrals of rational functions problems step by step online. Find the integral int((x-5)/(x^2+2x+-35))dx. Factor the trinomial x^2+2x-35 finding two numbers that multiply to form -35 and added form 2. Thus. Simplifying. We can solve the integral \int\frac{1}{x+7}dx by applying integration by substitution method (also called U-Substitution). First, we must identify a section within the integral with a new variable (let's call it u), which when substituted makes the integral easier. We see that x+7 it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part.
