$\begin{matrix}\left(5\right)\left(-9\right)=-45\\ \left(5\right)+\left(-9\right)=-4\end{matrix}$
Learn how to solve definite integrals problems step by step online. Integrate the function y/(y^2-4y+-45) from 12 to 15. Factor the trinomial y^2-4y-45 finding two numbers that multiply to form -45 and added form -4. Thus. 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).
