It seems no matter what I try after this I cannot get the answer in the book.
Any help would be greatly appreciated.
Clearing the fractions gives
First lets get our two freebee values
let x =1
Now we know that this is true for ALL VALUES OF X so we can pick some others. I will pick x=0 and x=2 to get a system of equations.
Now we need to solve
subtracing the 2nd from the first gives
There we go Yeah!!!
I hope this helps.
