hi i would really appreciate some help solving this question simultaneously:
Find A and B such that
x-11/(x+3)(2x-1)= A/x+3 + B/2x-1
Multiply both sides by (x+3)(2x-1) to get rid of the fractions.
We end up with this:
(x-11) = A(2x-1) + B(x+3)
You can solve for A and B more easily now.
I hope this helps and is what the problem was asking.
