Question

Simplify.
3x - x + 1
______ _______
2x - 5 2x + 5

Answer 1

Multiply both by each other's denominators. Then you have:
(3x(2x+5)-(x+1)(2x-5))/(2x-5)(2x+5)

Answer 2

3x x + 1 3x(2x+5)-(x+1)(2x-5) 6x^2+15x-2x^2+5x-2x+5
______ - _______=--------------------=------------------------------=
2x - 5 2x + 5 4x^2-25 4x^2-25

4x^2+18x+5
=--------------
4x^2-25
