Let's see, we're just gonna use the power rule a bunch of times. It's going to be three x squared plus two times four is eight. X to the two minus one is just one power, first power. So that's just, I can just write that as eight x. And then the derivative with respect to x of seven, well, derivative with respect to x of a constant is just gonna be zero. So that's u prime of x. So then I'm just gonna multiply by u prime of x, which is three x squared plus, three x squared plus eight x.
