Question 32954: Its actually the subtraction of unlike rational denominators.
The example in my phschool mathbook has the following rational expression:
_4_ _ __1__
5x x^2
Note: The 5x is the denominator for 4, and x^2 is the denominator to 1

__4x-5__
5x^2
but everytime I try to solve the problem itends up bieng:
__4x^2-5__
5x^2
What am I doing wrong?

4/5X-1/X~2 OR (4*X~2)-(X*5)/5X*X~2 OR (4X~2-5X)/5X~3 OR DIVIDING ALL TERMS BY X
WE GET (4X-5)/5X~2
