which shows one way to determine the factors of $x^{3}-12x^{2}-2x + 24$ by grouping?\n$x(x^{2}-12)+2(x^{2}-12)$\n$x(x^{2}-12)-2(x^{2}-12)$\n$x^{2}(x - 12)+2(x - 12)$\n$x^{2}(x - 12)-2(x - 12)$
Answer
Explanation:
Step1: Group the terms
Group the polynomial (x^{3}-12x^{2}-2x + 24) into two - groups: ((x^{3}-12x^{2})+(-2x + 24)).
Step2: Factor out the greatest common factor from each group
From the first group (x^{3}-12x^{2}), the greatest common factor is (x^{2}), so (x^{3}-12x^{2}=x^{2}(x - 12)). From the second group (-2x + 24), the greatest common factor is (-2), so (-2x + 24=-2(x - 12)).
Step3: Rewrite the polynomial
The polynomial ((x^{3}-12x^{2})+(-2x + 24)) can be rewritten as (x^{2}(x - 12)-2(x - 12)).
Answer:
(x^{2}(x - 12)-2(x - 12))
