Which shows one way to determine the factors of x3 – 12x2 – 2x + 24 by grouping?

x(x2 – 12) + 2(x2 – 12)
x(x2 – 12) – 2(x2 – 12)
x2(x – 12) + 2(x – 12)
x2(x – 12) – 2(x – 12)

Answer:

The last choice.

Explanation:

x3 – 12x2 – 2x + 24 Take out x2 and -2:

= x2(x – 12) - 2(x – 12).

The x - 12 is common to the 2 parts so the factors are:

(x2 + 2)(x - 12).
