Best ResponseYou've already chosen the best response.0It's actually (x + 4)(x  4), from a difference of squares Then you can write this \[\frac{ 5x+4 }{ (x+4)(x4) }=\frac{ A }{ x+4 }+\frac{ B }{ x4 }\] Then you have to multiply the whole equation by the denominator on the left side

Best ResponseYou've already chosen the best response.0no offense, I don't need to try khan academy I know how to do this. Your issue is that you factored the denominator wrong. http://www.wolframalpha.com/input/?i=factor+x%5E216

Best ResponseYou've already chosen the best response.0np and foil these out and you'll see \((x4)(x4)=x^28x+16\) \((x4)(x+4)=x^216\)
