+2%2F%28a-b%29+%2B+1%2F%28a%2Bb%29
Here's how to solve for this
Step 1. Multiply each term with the least common denominator. In this expression the LCD (Least Common Denominator) will be (a-b)(a+b)
+%28%28a-b%29%28a%2Bb%29%292%2F%28a-b%29+%2B+%28%28a-b%29%28a%2Bb%29%291%2F%28a%2Bb%29
In the first term a-b will be cancelled and in the second term a+b.
Our new expression now is
%282%28a%2Bb%29%29%2B+%281%28a-b%29%29
Combine like terms and simplify
%282a+%2B+2b%29+%2B+%28a+-+b%29
2a + a + 2b - b
3a + b
