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
Guided Practice = -
