$\int\frac{1}{x\left(1+x\right)\left(-1+x\right)}dx$
Learn how to solve differential equations problems step by step online. Find the integral int(1/(-x+x^3))dx. Rewrite the expression \frac{1}{-x+x^3} inside the integral in factored form. Rewrite the fraction \frac{1}{x\left(1+x\right)\left(-1+x\right)} in 3 simpler fractions using partial fraction decomposition. Expand the integral \int\left(\frac{-1}{x}+\frac{1}{2\left(1+x\right)}+\frac{1}{2\left(-1+x\right)}\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. We can solve the integral \int\frac{1}{2\left(1+x\right)}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 1+x it's a good candidate for substitution. Let's define a variable u and assign it to the choosen part.
