Hello, Thanks in advance for any help with this question.
I am fairly comfortable with these, however the minus on the numerator is throwing me off!
Question) Express as the sum of partial fractions:
-3 / (2x+1)(x-3)
Usually I would say A / (2x+1) + B / (x-3)
So that -3 = A(x -3) + B(2x+1) and then sub x = 3 so that A=0
Giving -3 = 0 + 7B
But that means B is a a complicated decimal!! -3/7 = -0.42857 which is no good!
Thanks again for any assitance.
