For a real number x, find the number of different possible values of x^2 - abs(x)^2.
+307 Answer: \(0\)
Solution:
\(x^2\) is always positive. So is the absolute value of x (which is then squared to get \(x^2\)). Since both sides of the expression are \(x^2\), there is only one possible answer for \(x^2-x^2\); \(0\).
