That the product rule; the formula for the derivative of (f/g) where f and g are functions of x. The brackets mean you square the whole function g(x). It's kinda redundant, but whatever. It can be derived with some fuckery, just the defn of derivative probably. OR, you can just never use it. Use the product rule and chain rules instead.
