Differentiate the function.
$ H(u) = (3u - 1)(u + 2) $
he has clears the when you read here. So we're gonna start with foil and we, uh, three. You square plus five year minus two. And after we derive this, we're going to use this sum indifference role to get D over. Deal three square plus de over. D'oh. Five u minus D over do you two. We know that the constant function, it goes to zero and we use our power role to get three times to you to the two minus one. Power plus five you to the one minus one Power. This is equal to six year plus five.
