Question

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 1

Answer:

D. $x^{2} (x-12) -2(x-12)$

Step-by-step explanation:

Determine the groups: $(x^{3}-12x^{2} )$ - $(2x+24)$

Factor out terms: $x^{2} (x-12) -2(x-12)$

The -2 was factored out in the second group to ensure that both groups had

(x-12).
