Answer:
Both equations have the same result. (x - 3) (4 x^2 + 7)
Explanation:
Factor the following:
4 x^3 - 12 x^2 + 7 x - 21
Factor terms by grouping. 4 x^3 - 12 x^2 + 7 x - 21 = (4 x^3 - 12 x^2) + (7 x - 21) = 4 x^2 (x - 3) + 7 (x - 3):
4 x^2 (x - 3) + 7 (x - 3)
Factor x - 3 from 4 x^2 (x - 3) + 7 (x - 3):
Answer: (x - 3) (4 x^2 + 7)
