Explanation:
We're dealing with a rational function here, which tells us to use the quotient rule.
Our function is made up of two functions:
The Quotient Rule tells us that the derivative will be:
Now, we just plug in. We get:
Our final answer being in purple.
We just had to realize we're dealing with a rational function, so we had to use the Quotient Rule. We find our two functions, their derivative, and plug into the formula.
Hope this helps!
