Do you know what an extraneous solution is?

anonymous · Answer

Yea, you get a solution but it doesn't work into the original equation

anonymous · Answer

$$x - 7 = \sqrt{x} $$

anonymous · Answer

That could be one but i don't know how to work it

vampirediaries · Answer

I think it would be easier to solve a problem if it didn't have the square root.
And I'm not even sure I've seen an extraneous solution with a square root in the equation.

http://www.mathwords.com/e/extraneous_solution.htm I was just going to use 7 instead of 6

vampirediaries · Answer

$$2\left| x-7 \right|=x-8$$

vampirediaries · Answer

I think this would be better:$$\left| 3x+2 \right|=4x+5$$

Do you think you can solve these extraneous equations?
