I do not understand the notation.

Do you mean is x*x always greater than x*2?

If so, chose any number in the open interval (0,2) and test it:

0.5 * 0.5 = 0.25 < 1 = 0.5 * 2 1.5 * 1.5 = 2.25 < 3 = 1.5 * 2

In general,

x*x > x*2 = x > 2 provided x > 0

Otherwise, please provide a reference to your notation.

HTH,

Kevin

PS Graphing the values is a great place to start.
