if x does not equal 0, is x^2>0

@rickg had it right that if it is a real number, then x^2 > 0.
However your question doesn't specify that x is a real number.
Any non-real number squared will give you a negative number (I think)
For example:
i = square root (-1)
if x = i then x^2 = -1

M$Equivalently, say that for all real numbers x, x^2 >= 0, and equality occurs if and only if x=0..

M$Decimal values can approach zero, but will never reach zero. For instance, .2 squared is .04, point .04 squared is .0016, and so on. This number will get very small, but will always be above zero.
