Which of the following quadratic expressions is identified as the product of two conjugate binomials?

Answer and explanation

Correct answer: \(p^2-q^2\)

The conjugate binomials \((p+q)\) and \((p-q)\) give \((p+q)(p-q)=p^2-q^2\), as the middle terms cancel. Option B is a binomial square. Exam tip: opposite signs with matching terms indicate a difference of squares.
