How do you add/subtract rational expressions? ...

There are a few steps to follow when you add or subtract rational expressions with unlike denominators.

1.To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. ...

2.Write each expression using the LCD. ...

3.Add or subtract the numerators.

4.Simplify as needed

Step-by-step explanation:

copy the denominator and add/subtract the numerator

To add (or subtract) two or more rational expressions with the same denominators, add (or subtract) the numerators and place the result over the denominator. ac−bc=a−bc .

To add (or subtract) two or more rational expressions with the same denominators, add (or subtract) the numerators and place the result over the denominator.

Example:

Add nn+3+2n+3 .

Since the denominators are the same, just add the numerators.

nn+3+2n+3=n+2n+3
