I would first rewrite the function as follows:
Now, differentiation is a bit simpler.
I'm doing a seemingly simple problem for h.w
The question is to differentiate (u − squareroot of u)(u+ squareroot of u)
After applying the product rule I get 2u-1-u^1/2 However when I input it the h.w says it's wrong. can someone please help me?
Of course, MarkFL2 is correct. The derivative is the same no matter how you find it, so you may as well find it the easiest way. But if you really want to use the product rule, here it is:
