Add or subtract the numerators.
The LCM of the denominators of fraction or rational expressions is also called least common denominator or LCD. When subtracting notice that the subtraction sign is moved into the numerator so it can be distributed later if needed. Adding rational expressions together.
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. If they have a common denominator just add the numerators together and simplify. The same principles apply when addingaddingadding or subtracting rational expressions subtracting rational expressionssubtracting rational expressions containing variables.
Write each expression using the LCD. Adding and Subtracting with Like Denominators. Subtract and state the difference in simplest form x 5.
