Add rational expressions with different denominators
Adding Rational Expressions
Students learn that when adding rational expressions,, the first step is to factor each of the denominators, if possible, then give each term a common denominator by multiplying the numerator and denominator of each term by the appropriate value. Next, add across the numerators and keep the denominators the same. Finally, factor the resulting numerator, if possible, to determine if the rational expression can be reduced.
