Addition of Rational Expression
1. Find the LCD = (a-b)(a+b)
+2%2F%28a-b%29+%2B+1%2F%28a%2Bb%29+


2. You cannot add nor subtract rational expression with different denominator.Write an equivalent expression with the LCD.


2%28a%2Bb%29%2F%28a-b%29%28a%2Bb%29+%2B+%28a-b%29%2F%28a-b%29%28a%2Bb%29


Combine like terms in the numerator and simplify
%282a+%2B+2b+%2B+a+-+b%29%2F%28%28a-b%29%28a%2Bb%29%29

highlight+%28%283a+%2B+b%29%2F%28a%5E2+-+b%5E2%29%29
