In this lesson, students learn how to add and subtract algebraic fractions by getting a common denominator. The first step is to rewrite each fraction so that each denominator is factored. Then, if any factors are missing, you need to multiply the numerator and denominator of the fraction by those missing factors. Once you have a common denominator, you can add or subtract the numerators, simplifying them if necessary. Finally, check to see if you can factor and cancel out anything in the numerator and denominator.
