#### Explanation:

We have

We can differentiate it by two methods:

*Method 1:*

We will use the quotient rule, there is a way I like to remember it:

*Denominator same, differentiation of numerator. Minus numerator same, differentiation of denominator whole divided by denominator squared*

Differentiating with respect to x:

*Method 2:*

Simplifying:

We can now apply the product rule, there is a way I like to remember it:

*First function same, differentiation of second function. Plus second function same, differentiation of first function*

Differentiating with respect to x:

Rearranging the terms, we get:

I hope it helps!
