Lesson P6 – Day 3 Adding and Subtracting Rational Expressions with like denominators The steps are as follows: 1.Get a common denominator. 2.Add or subtract the numerators. 2.Place the result over the common denominator. 3.Simplify if possible.
Example 1: Distribute negative. Combine like terms. Place result over common denominator Cancel out like factors. State the excluded values. Factor numerator and denominator State domain.(excluded values) Simplify. Common Denominators
