Question 16 • Crowley Summer 26 Credit Recovery Algebra 2 A

Which is the completely factored form of 12x3 – 60x2 + 4x – 20?

Answer

A

4(3x2 – 1)(x – 5)

B

4x(3x2 + 1)(x – 5)

C

4x(3x2 – 1)(x + 5)

D

4(3x2 + 1)(x – 5)

Explanation

Factor out 4 to get 4(3x³ − 15x² + x − 5). Group the terms: 4[3x²(x − 5) + 1(x − 5)] = 4(3x² + 1)(x − 5), which is choice D.
