- Find Least Common Denominator.
- To rewrite each rational expression with LCD in above step as denominator.
- Perform addition/subtraction.
Calculation:
In order to add/subtract rational expressions follow three steps
For example consider the rational expressions
First find the Least Common Denominators, as
Thus, least common denominator is
Now, the above rational expressions can be added by writing the denominators as LCD as:
Thus,
