It decomposes into the form A/x + B/(x^2) + C/(2x-1)

Find A,B and C

thx for the reply, i know but i want to when finding c
why is the equation

0=a+2c

and not 1=a+2c when it suppose to be this one.

so why 0 and not 1

also to confirm is a= 4 and b=-1

Getting the fractions as one, you should get (Ax+B)(2x-1)+C(x^2) as the numerator, which expands into (2A+C)x^2+(2B-A)x-B

Clearly, there should be no x^2 or x term in the numerator, so we set 2A+C=0.
Similarly, 2B-A=0.
