Which of the following algebraic identities gives the standard form of the product of two binomials that differ only in the sign of the second term, such as \\(p+q\\) and \\(p-q\\)?

Answer and explanation

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

In \\((p+q)(p-q)\\), the cross terms \\(pq\\) and \\(-pq\\) cancel, leaving only \\(p^2-q^2\\). Option B is the identity for a perfect-square trinomial. Exam tip: opposite signs in matching binomials signal a difference of squares.
