How do you check for extraneous solutions?

- =

In this lesson you will learn to identify extraneous solutions in rational equations by checking

solutions.

Let’s Review

x = …?

A Common Mistake

Core Lesson - =

=

=

5x(x+2)* =5x(x+2)*

Core Lesson 10x2-10x = x2 + 2x

9x2-12x = 0

3x(3x-4) = 0

x =0, - =

In this lesson you have learned to identify extraneous solutions

in rational equations by checking solutions
