0 Perhaps check it again Posted February 6, 2014 Report Share Posted February 6, 2014 Options 1) You can't have ambiguity. You can't have "2x squared" meaning (2x) squared = 4x2 and have "4x squared" meaning 4x2 also. 2) "x" and "X" are different cases of the same letter, and therefore they represent different variables. So, it would be consistent for those two equations to exist, because you have two different variables in them. Quote Link to comment Share on other sites More sharing options...
