Homework Help: HELP MATH

Posted by cassii on Tuesday, August 8, 2006 at 1:16pm.

how would u simplify this problem i think it is
am i right
the problem is
5 4 3
_ + ___ - ___
x x^2 x^3

I'm going to assume your problem is this:

5/x + 4/x^2 - 3/x^3

To simplify, find a common denominator, which is x^3 in this case.

Using the common denominator:

5x^2/x^3 + 4x/x^3 - 3/x^3 =

(5x^2 + 4x - 3)/x^3

And that's as far as you can go on this one.

so wait the answer would be 5over x^2 plus 4over x minus 3 then all of that over x^3 ?

thanks a ton
