Writing Polynomial Functions from Complex Roots

Question 3 • [INMT3] Integrated Math 3 Sem 1 (26-27)

Expand the expression.2x2(x + 3)(x–2)

Answer
A
2x3 + 2x2 – 12x
B
4x3 + 6x2 – 4x2
C
2x4 + 2x3 – 12x2

Explanation

First multiply the binomials: (x + 3)(x − 2) = x² + x − 6. Then multiply each term by 2x² to get 2x⁴ + 2x³ − 12x². This matches choice C, “2x⁴ + 2x³ − 12x².”
