Homework Statement
(x^(3)+2x) / (x^(2)-5) d/dx = ?
Homework Equations
d/dx (f/g) = (g d/dx (f) - f d/dx (g)) / g^2
The Attempt at a Solution
d/dx y = { (x^(2)-5) d/dx (x^(3)+2x) - (x^(3)+2x) d/dx (x^(2)-5) } / (x^(2)-5)^2
This is where it gets complicated for me.
{ (x^(2)-5)(2x^(2)+2) - (x^(3)+2x)(2x) } / (x^(2)-5)^2
I am pretty sure this is at least close, if it is wrong please tell me where I went wrong, and if it is right but not simplified can you explain how to simplify it further.
Thank you in advance, I hope that I gave you appropriate information.
