Answer:
Step-by-step explanation:
This equation may look difficult, but let's take it step by step. We are given the equation
.
We can simplify this to
through the difference of two squares formula. Now, we need to make the denominators the same, so:
We can finally combine the fractions since they have the same denominator:
We distribute the negative: 
From here, we combine like terms: 
There's still one more step, we can factor out a two from the numerator:
so that we can cancel out the term (x+y).
We are left with
