FOIL - First, outside, inside, last.
To elaborate: Whenever you solve a problem like (a + b) (c + d), you multiply the First terms of each bracket, then the Outside terms, then the Inside terms, then the Last terms of each bracket.
(2x + 1) (x - 2)
First: (2x)(x)
Outside: (2x)(-2)
Inside: (1)(x)
Last: (1)(-2)
Add them together.
(2x)(x) + (2x)(-2) + (1)(x) + (1)(-2)
2x^2 - 4x + x - 2
And the final answer is
2x^2 - 3x - 2
Edit: My mistake. I read your question wrong.
To solve (2x + 1)/(x - 2), you have to use long division.
Your answer should be:
-3/(x-2) + 2

(2x+1)(x-2)=2x(x-2)+1(x-2)
=2x^2-4x+x-1
=2x^2-3x-1

A question with not enough information...
What are you trying to find out? If you want to know what X is, you need the equation to equal something. We can't assume anything.

It's an algebra expression involving the variable x. That's what it is.
Would you like to solve some kind of problem using this expression? What is that problem?
