And so this is going to be equal to four times two x plus one which is equal to, if we wanna distribute the four, we could say it's eight x plus four. That's a completely legitimate way of doing it. Now there are other ways of doing it. You could expand out two x plus one squared. You could say, hey, this is the same thing as the derivative with respect to x of two x squared is going to be four x squared, and then two times the product of these terms is gonna be plus four x plus one. And now you would just apply the power rule. So a little bit of extra algebra up front, but you can just go straight forward with the power rule, and you're gonna get this exact same thing.
