If x is a real number, what type of statement is x² ≥ 0?

Answer and explanation

Correct answer: Always true

The square of every real number is zero or positive. Therefore, x² ≥ 0 is true for every real x: x² = 0 when x = 0 and x² > 0 when x ≠ 0. Options C and D are incorrect because the statement is also true for negative and positive values, as well as for zero. Exam tip: When evaluating an inequality involving a square, always check the case x = 0.
