Question 536096: I asked a very similar question just a minute ago and this problem I am stuck on the same exact spot in the problem as I was in the first one..
7/x - 6x/x^2-64 + 4/x+8
When I did the / mark that means over the next numbers following it, it is fractions

7/x - 6x/x^2-64 + 4/x+8
When I did the / mark that means over the next numbers following it, it is fractions
-------------
I think you mean
7%2Fx+-+6x%2F%28x%5E2-64%29+%2B+4%2F%28x%2B8%29
Use parentheses for clarity:
7/x - 6x/(x^2-64) + 4/(x+8)
--------------------
Find a common den
x(x^2 - 64) works, since x+8 is a factor of x^2-64
------------
= 7%28x%5E2-64%29%2Fden+-+6x%2Ax%2Fden+%2B+4%2Ax%2A%28x-8%29%2Fden
= %287x%5E2-448+-+6x%5E2+%2B+4x%5E2+-+32x%29%2Fden
= %285x%5E2+-32x+-448%29%2F%28x%5E3+-+64x%29
