Adv Algebra: Solving Radical Equations 255

This lesson is part of the series: Advanced Algebra

This 83 minute advanced algebra lesson teaches how to solve radical equations (equations where the variable appears in the radicand, for example: the square root of (x+12)= 3 that results in a linear equation, or the square root of (x+4) + 8 = x, that result in a quadratic equation.

This lesson will teach you how to solve radical equations involving:
- square root with one radical
- cube root with one radical
- square root with two radicals, for example: square root (3x+1) + square root (x-1) = 6

You will also learn to:
- isolate the radical
- square both sides
- simplify
- solve the equation
- check for extraneous roots
- write the real roots

This lesson contains explanations of the concepts and 18 example questions with step by step solutions plus 5 interactive review questions with solutions.

Lessons that will help you with the fundamentals of this lesson include:
- 160 Operations With Radicals (http://www.mindbites.com/lesson/5065)
- 230 Solving Quadratic Equations by Factoring (http://www.mindbites.com/lesson/5087)
- 235 Solving Quadratic Equations Using the Quadratic Formula (http://www.mindbites.com/lesson/5084)

All lessons have been prepared by a certified teacher, B.A., B. Ed. (Math Major) with 30+ years experience teaching Math to High School Students and Continuing Education learners.
