$\int\left(\frac{a}{x+1}+\frac{b}{x+2}+\frac{c}{x+4}\right)dx$
Learn how to solve integral calculus problems step by step online. Integrate the function a/(x+1)+b/(x+2)c/(x+4). Find the integral. Expand the integral \int\left(\frac{a}{x+1}+\frac{b}{x+2}+\frac{c}{x+4}\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. Rewrite the fraction \frac{a}{x+1} inside the integral as the product of two functions: \frac{1}{x+1}a. We can solve the integral \int\frac{1}{x+1}adx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula.
