Hi sir this is really minimal as it only equates to one mark but in the markscheme they have said if the plane equation is left in the form x+y+z=c, then they will only give the working out mark and no mark for the answer which doesn’t make sense to me? Does it have to be in the form x+y+z-c=0 always to get the final mark? Thanks for the excellent video
