Quizplus · Accepted Answer

The trinomial has a leading coefficient of 4, suggesting that the polynomial form will have terms with coefficients that are multiples of 4. Adding 12x and subtracting 3x will allow for grouping of the middle terms to form two binomials, resulting in a polynomial with 4 terms. Therefore, the correct answer is D.
