$\int\frac{x^4+6x^2-7}{x^4+8x^2-9}dx$
Learn how to solve problems step by step online. Find the integral of (x^4+6x^2+-7)/(x^4+8x^2+-9). Find the integral. Divide x^4+6x^2-7 by x^4+8x^2-9. Resulting polynomial. Expand the integral \int\left(1+\frac{-2x^{2}+2}{x^4+8x^2-9}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately.
