SUMMARY
The discussion focuses on solving the inequality \( x^2 \geq [x]^2 \), where \([x]\) represents the Greatest Integer Function and \(\{x\}\) denotes the Fractional Part. The solution involves manipulating the expression to \( x^2 - [x]^2 \geq 0 \) and factoring it as \((x + [x])(x - [x]) \geq 0\). The key conclusion is that the solution set for \(x\) is \( x \in (-\infty, -[x]] \cup [[x], \infty) \), clarifying the conditions under which the inequality holds.
