Hi, I'm just wondering if anyone can help me with this equation: I need to determine the values of A,B and C from the given equation.
[tex]\frac{A}{(x-1)}[/tex] + [tex]\frac{B}{(x+1)}[/tex] + [tex]\frac{C}{x}[/tex] = [tex]\frac{5x^2+2x+1}{x^3-x}[/tex]
I've tried to simplify it by factorising the denominator on the LHS to x^3 - x, and i am suspicious that the values of A,B and C are the 3 parts of the numerator of the RHS respectively to 5x^2,2x and 1.
Thanks
