plz i cerious need help i posted dis qustion bt due 2 my wrong typing it was nt anser plz here it is:x^4+3x-2/(x^2+1)=Ax+B/(x^2+1)+Cx+D/(x^2+1)^2+(Ex+F)/(x^2+1)^3+G/(x-4)+(Hx+1)/(x-4)^2.find ABCDEFGH? plz it a partial fraction thank yo u and Godbless u

Answer 1

You appear to want

x^4+3x-2
--------------------------
(x^2+1)^3 (x-4)^2

You manage to mangle things badly, and the solution to that fraction has been posted in response to an earlier version of the poorly typed question. Here it is again.

http://www.wolframalpha.com/input/?i=%28x^4%2B3x-2%29%2F%28%28x^2%2B1%29^3+%28x-4%29^2%29

just scroll down a bit to see the partial fraction expression.
