1. ## integral

plz help integrate

5x^2+4x+54
over
(x-4)(x^2+9)

i broke it into parts and it becomes
6/(x-4)-x/(x^2+9)

2. ## integral

$\int \left( \frac{6}{x - 4} - \frac{x}{x^2 + 9} \right) \,dx$

Both fractions can be integrating using the rule: $\int \frac{f\,'\,(x)}{f\,(x)} \,dx= ln[f(x)] + c$
