This 74 minute basic algebra lesson follows on from 135 Solving Linear Equations Part I to help you solve more difficult linear equations. Identities and word problems on the area of rectangles are also covered. This lesson will teach you how to solve:
- equations with the distributive property
- equations with multiplication of binomials (FOIL) like this: (4m^2) - 2(2m-3)(4m+1) = -4
- equations with special products like the difference of squares or perfect squares
- mixture problems
- identities
- word problems involving rectangles and squares
This lesson contains explanations of the concepts and 22 example questions with step by step solutions plus 6 interactive review questions with solutions.
