simplify 2/x + 3x+1/x^2 + x-2/x^3 ?

It's impossible to tell what parts are in the numerators and what parts are in the denominators, but this might be the problem:
..2 ... .. 3x + 1 .......x - 2
----- + ----------- + --------
..x .... .... x² .......... x³
1) Clear the fractions by multiplying all three terms by the LCD of x³ and letting the denominators cancel as much as they can.
After you have multiplied and canceled, you get this:
2x² + x ( 3x + 1 ) + x - 2
2) Clear the parentheses by distributing the x
2x² + 3x² + x + x - 2
3) Combine like terms
5x² + 2x - 2 <-- answer

First, it depends on where you ASSUME the INVISIBLE parentheses are. It is not enough to use space / no space as a delimiter.
