$3\int\frac{1}{-1+x^2}dx$
Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int(3/(x^2-1))dx. The integral of a function times a constant (3) is equal to the constant times the integral of the function. Factor the difference of squares -1+x^2 as the product of two conjugated binomials. Rewrite the fraction \frac{1}{\left(1+x\right)\left(-1+x\right)} in 2 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B. The first step is to multiply both sides of the equation from the previous step by \left(1+x\right)\left(-1+x\right).
