Splitting into partial fractions:
So, multiplying both sides by we have:
(multiplied it out)
If we write the left hand side as a quadratic:
We can equate the coefficients to see that:
So this should be an easy system to solve for and you should be on your way.
Edit: Ok a little too late lol xD.
helped, since it's located in the denominator. Then I thought in after subtraction I saw that I was doing worked out, besides it's the difference of perfect squares. Finally by seeing the in the denominator I could make it.
I'm sorry if this explanation looks terrible, but it's pretty hard to explain what I did in a couple of seconds.
