What will be the expanded form of ((p-2)(p+7))?

Answer and explanation

Correct answer: \(p^2+5p-14\)

Using the distributive property, \((p-2)(p+7)=p^2+7p-2p-14=p^2+5p-14\). Hence, option D is correct. In option A, the sign of the middle term is incorrect because \(7p-2p=5p\), not \(-5p\). Exam tip: multiply each term of one binomial by both terms of the other, then combine like terms.
