Homework Statement
[itex]\frac{x}{(x+4)^{2}}[/itex]
Homework Equations
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!
