Hi

How do i solve this partial fraction:

I tried using the same method as I did before...

Let x = -1

4+2 = 2A

6 = 2A

A = 3

Differentiate both sides.

8x - 2 = 2Ax + B

Substitute in A = 3

8x - 2 = 6x + B

2x-2 = B

I keep on getting 2x - 2 as the value for B even though it's meant to be x - 3.

Could someone please point out what i did wrong?
