Well, that just means that this first term right over here, that's going to be equivalent to 3 times the derivative with respect to x of f of x plus this part over here is the same thing as 2. Let me make sure I don't run out of space here. Plus 2 times the derivative with respect to x of g of x. So the derivative of h with respect to x is equal to 3 times the derivative of f with respect to x plus 2 times the derivative of g with respect to x. And if we wanted to write it in this kind of prime notation here, we could rewrite it as h prime of x is equal to 3 times f prime of x. So this whole part right over here, that is the same thing as f prime of x. So it's 3 times f prime of x plus 2 times g prime of x.
