\( 1 \leftarrow \) Divide the expression using the quotient rule.

To use the quotient rule for differentiation, remember that it states \( \frac{d}{dx}\left(\frac{u}{v}\right) = \frac{v \frac{du}{dx} - u \frac{dv}{dx}}{v^2} \), where \( u \) and \( v \) are both functions of \( x \). So, if you have the expression \( \frac{f(x)}{g(x)} \), calculate the derivatives \( f'(x) \) and \( g'(x) \), then plug them into the formula for the quotient rule. Next, ensure that \( v \neq 0 \) in the original function, as division by zero is a no-go! Also, keep an eye out for simplification opportunities; often, after applying the quotient rule, you can factor or cancel terms to make your final derivative tidier.
