$\int_{12}^{15}\frac{y}{\left(y+5\right)\left(y-9\right)}dy$
Learn how to solve problems step by step online. Integrate the function y/(y^2-4y+-45) from 12 to 15. Rewrite the expression \frac{y}{y^2-4y-45} inside the integral in factored form. Rewrite the fraction \frac{y}{\left(y+5\right)\left(y-9\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(y+5\right)\left(y-9\right). Multiplying polynomials.
