"some questions". We can't read your mind.

anonymous · Answer

John and Tim are looking at the equation sqrt (3x + 4) = x. John says the solution is extraneous. Tim says the solution is non-extraneous. Is John correct? Is Tim Correct? Are they both correct? Justify your response by solving this equation, explaining each step with complete sentences.

I know its a problem that its correct, but it doesn't work in the original equation, and also doesn't fit in within the limits of the problem.

What are you taking about?

I was saying what a extraneous solution is? I thought that is what you were asking

primeralph · Answer

Okay, hold on.

primeralph · Answer

I'll solve it, and you'll do the "explaining each step" part.
