## Formula for adding and subtracting rational expressions

To add or subtract rational expressions, first make sure that the denominators are the same. If they are not, then rewrite the fractions so that the denominators are the same. Next, add or subtract the numerators, and then simplify the result.

For example, to add the fractions

2/3 + 1/4

first rewrite them as

6/12 + 1/12

Next, add the numerators, which gives

7/12

Finally, simplify the fraction to

7/12 = 1/2

## Adding And Subtracting Rational Expressions Definition

Adding and subtracting rational expressions is a mathematical process that allows two or more rational expressions to be combined into a single expression. This process is accomplished by adding or subtracting the numerators of the rational expressions and then simplifying the resulting expression.

## Example of adding and subtracting rational expressions based on Formula

The sum of two rational expressions is given by the formula:

(a/b) + (c/d) = (ad + bc)/bd

where a, b, c, and d are the coefficients of the rational expressions.

For example, if the two rational expressions are (2/3) + (4/5), then the sum is given by (2/3) + (4/5) = (2*5 + 4*3)/(3*5) = (10 + 12)/15 = 22/15.

The difference of two rational expressions is given by the formula:

(a/b) – (c/d) = (ad – bc)/bd

where a, b, c, and d are the coefficients of the rational expressions.

For example, if the two rational expressions are (2/3) – (4/5), then the difference is given by (2/3) – (4/5) = (2*5 – 4*3)/(3*5) = (10 – 12)/15 = -2/15.
