Hi there montenegro3, welcome to MHF!

To differentiate this function you must employ the product rule.

It states that if

in your case make and

find and and apply the rule

Use the quotient rule here, it states if

For

in your case make and

find and and apply the rule - Dec 19th 2009, 12:46 AMmatheagle
Instead of the quotient rule, you should rewrite that ratio as...

Hence the derivative is
