$\int\frac{4}{x^2-4}dx$
Learn how to solve integrals by partial fraction expansion problems step by step online. Find the integral int(4/(xx^1/2^2-4))dx. Simplify the expression inside the integral. Factor the difference of squares x^2-4 as the product of two conjugated binomials. Rewrite the fraction \frac{4}{\left(x+2\right)\left(x-2\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(x+2\right)\left(x-2\right).
