$\int\frac{\frac{3x-6}{x^2+21x+54}}{\frac{40x^2}{x^2+6x+9}}dx$
Learn how to solve integral calculus problems step by step online. Find the integral of ((3x-6)/(x^2+21x+54))/((40x^2)/(x^2+6x+9)). Find the integral. Simplify the fraction \frac{\frac{3x-6}{x^2+21x+54}}{\frac{40x^2}{x^2+6x+9}}. Factor the trinomial \left(x^2+21x+54\right) finding two numbers that multiply to form 54 and added form 21. Thus.
