If anyone could answer a question, I would appreciate it.

I'm working on solving using partial fractions.

Here's a summary of my work: which leads to .

Letting x = -1 yields -3B = 6, B = -2. Letting x = 1/2 yields 9/2 = 3/2A, or A = 3. This gives an integral with partial fractions: which gives 3ln|2x-1|-2ln|x+1| + C.

The text answer is (3/2)ln|2x-1|-2ln|x+1| + C. What am I missing?
