$\frac{7}{\left(x-9\right)\left(x^2+4\right)}=\frac{A}{x-9}+\frac{Bx+C}{x^2+4}$
Learn how to solve definite integrals problems step by step online. Integrate the function 7/((x-9)(x^2+4)) from -infinity to 7. Rewrite the fraction \frac{7}{\left(x-9\right)\left(x^2+4\right)} in 2 simpler fractions using partial fraction decomposition. Find the values for the unknown coefficients: A, B, C. The first step is to multiply both sides of the equation from the previous step by \left(x-9\right)\left(x^2+4\right). Multiplying polynomials. Simplifying.
