Lesson 10.4:
*Radical equations ­ equations that contain variables in the radicand
**To solve them,
­­isolate the variable on ones side of the equation first
­­then square each side of the equation to eliminate the radical
­­then finish it
***Sometimes when you square each side of the equation, you could
have "extraneous solutions" [ones that aren't true solutions and don't
work in the equation].
