You're doing fine if "solving" the equation is all you have to do.  If x-2=0, what is x?

However, note that this rational function is undefined if x=1.

Again i ask you to clarify what you are supposed to do.

andrewishere · Answer

I am just supposed to find the value of x. I do know the answer is x=2 by just knowing, but I never really understood the steps to get there. What happened to the denominator?

When you set that fraction = to 0, you are actually setting only the numerator = to 0.
That gives you x=2.  End.

Sorry, but I need to get off the 'Net.  Perhaps we'll work together again later on.
