Can somebody help me create an extraneous question?

OpenStudy (anonymous):

@Loser66 @ganeshie8 This is my last question .-.

OpenStudy (vampirediaries):

Do you know what an extraneous solution is?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

\[x - 7 = \sqrt{x} \]

OpenStudy (anonymous):

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

OpenStudy (vampirediaries):

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

OpenStudy (vampirediaries):

\[2\left| x-7 \right|=x-8\]

OpenStudy (vampirediaries):

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

OpenStudy (vampirediaries):

Do you think you can solve these extraneous equations?
