In which expression is 3p a common factor of every term?

Answer and explanation

Correct answer: 3p² + 12p

The correct answer is A: 3p² + 12p. A common factor must divide every term of an expression. In the first term, 3p² ÷ 3p = p. In the second term, 12p ÷ 3p = 4. Therefore both terms contain 3p, and the expression can be written as 3p(p + 4). Option B is not correct because 12 has no factor p; 12 ÷ 3p is not a polynomial term. Option C is not correct because p² has coefficient 1, so it is not divisible by 3p. Option D is not correct because 9 has no factor p, even though 6p² is divisible by 3p. Option A is confirmed by expanding 3p(p + 4) = 3p² + 12p. Memory cue: a factor is common only when it appears in every single term, not merely in one term or most terms.
