Answer:

Step-by-step explanation:
So we want to find the derivative of the rational equation:

First, recall the quotient rule:

Let f be x^2-2x and let g be x^3+3.
Calculate the derivatives of each:


So:

Use the above format:

And that's our answer :)
(If you want to, you can also expand. However, no terms will be canceled.)
Isolate x. First add 10 to both sides
8x=x+21
Then subtract x from both sides
7x=21
Then divide both sides by 7
x=3
Final answer: x=3
