0 Posted 6 Feb 2014 · Report post Options 1) You can't have ambiguity. You can't have "2x squared" meaning (2x) squared = 4x^{2} and have "4x squared" meaning 4x^{2} 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. 0 Share this post Link to post Share on other sites
