thank you great video :) Question: are you allowed to sub x=-1.5 in to f'(x) and prove the graident is 0. Or do we have to do it your way as we are not allowed to use the -1.5 as they are asking you to prove it. Also another unrelated question in level 2 do you need to show the working out for how you solve the quadratic like the qudratic formula working out or can you just right the soultions
