**1. The problem statement, all variables and given/known data**

[itex]\frac{x}{(x+4)^{2}}[/itex]

**2. Relevant equations**

**3. The attempt at a solution**

I make the integrand equal to the following:

[itex]\frac{A}{(x+4)}[/itex]+[itex]\frac{Bx+C}{(x+4)^{2}}[/itex]

Then after finding a common denominator I get

x = A(x+4)[itex]^{2}[/itex]+(Bx+C)(x+4)

But that cannot be possible because when you set x=-4, you get -4=0. Any help please?

Also if you have ANY tips whatsoever about partial fractions please tell me them!
