Best ResponseYou've already chosen the best response.0The derivative I found is 3x^2 4x +5. After that I make the whole thing equal to four? Then I would subtract the 5 but after that what?

Best ResponseYou've already chosen the best response.1i think you are lucky here in that this problem has been cooked so the quadratic factors, but you can always use the quadratic formula to solve any quadratic equation
