Which of the following expressions can be identified as the square of a binomial?

Answer and explanation

Correct answer: \(16p^2-24pq+9q^2\)

A has end terms \((4p)^2\), \((3q)^2\) and middle term \(-2(4p)(3q)=-24pq\), so it is \((4p-3q)^2\). B has a negative final term. Tip: check the middle-term sign.
