Undefined is a term used when a mathematical result has no meaning. More precisely, undefined values occur when an expression is evaluated for input values outside of its domain. ( 1 if no complex numbers) ( 2 if no complex numbers) ( units in radians, no complex infinity)
No Solution would mean that X = undefined. X = 0 means that X is exactly equal to the the quantity of 0. It can't be anything else, if it's 0. If it's all answers, either X = 0 and X = 1 and X = 2 and on and on, since it can be anything. If it's one answer, then it is that answer. In this case, X = 0. X does not equal anything else.
