Adding and Subtracting Rational Expressions with Common and Unlike Denominators

A lesson on how to add and subtract rational expressions by either adding numerators or first finding a common denominator and then adding the numerators. Factoring and simplifying skill are also reviewed. INTRO 00:00 ADDING WITH COMMON DENOMINATOR EXAMPLE 1 01:12 EXAMPLE 2 02:58 ADDING WITH UNLIKE DENOMINATORS 04:38 EXAMPLE 1 07:13 EXAMPLE 2 10:20 PRACTICE 03:10 NOTE: There is an error made around the 2 minute marker. A binomial of (x + 5) is written down as the answer to a factoring situation, but it should have instead been an (x - 5). This will not affect what needs to be cancelled out in the problem conceptually.
