Adding AND Subtracting Rational Expressions Honors Algebra II Keeper

Adding or Subtracting Rational Expressions Step 1. If the denominators are the same, add or subtract the numerators. Place the result over the common denominator. If the denominators are different, first find the least common denominator. Write all rational expressions with this least common denominator, and then add or subtract the numerators. Place the result over the common denominator. Step 2. Simplify . Write all answers in lowest terms.
