So the first thing I'm gonna do is let's take the derivative of both sides. So we could say the derivative with respect to x of f of x, of f of x, is equal to the derivative with respect to x, the derivative with respect to x, of x to the fifth, x to the fifth, plus two, plus two x to the third, minus x squared. And so the notation, just to get familiar with it, you could view this as the derivative operator. This says, look, I wanna take the derivative of whatever is inside of the parentheses with respect to x. So the derivative of f with respect to x, we could use a notation that that is just f prime of, f prime of x. And that is going to be equal to, now here we can use our derivative properties. The derivative of the sum or difference of a bunch of things is just the derivative of, is equal to the sum or the difference of the derivative of each of them.
