Homework Statement
∫(7x^2+22x-54)/((x-2)(x+4)(x-1)) dx
Homework Equations
Partial functions
The Attempt at a Solution
∫(7x^2+22x-54)/((x-2)(x+4)(x-1)) dx = ∫(Ax)/(x2+2x-8) + B/(x-1)
= ∫A(x-1)dx + ∫B(x^2+2x-8)dx
Or is it:
= ∫(AX+B)/(x^2-2x-8) dx + ∫ C/(x-1)dx
Have I done the separation of the numerator and denominators right? I'm stuck right about here..I don't know what Bx2 equals to. 7? That doesn't seem to make sense, I must have done something wrong earlier.
Please help, thanks!
