Yes there is another way.
For starters, you should actually have gotten
Solve these equations simultaneously to find .
I'm a little rusty with my partial fractions so I just need a refresher.
The equation is I have
Then common denominators
After this can I do where, x=-2 for example? Cause then I will get 0=-2B
And then keep plugging in values for x? Or is there another way which I complete forgot about
1. Find the correct partial fraction decomposition.
2. Write out the first few terms ( I suggest at least the first four terms) and start cancelling in the usual way.
If you take greater care with the details you will probably have better luck in solving questions like this one.
