Which expression represents the square of the number (4) less than (x)?

Answer and explanation

Correct answer: (x-4)^2

The number 4 less than x is x-4. Since the question asks for the square of this entire number, the correct expression is (x-4)^2. The expression x^2-4 subtracts 4 only from the square of x; it is not the square of x-4. Exam tip: When a phrase asks for the square of a complete expression, place it in brackets before writing the exponent 2.
