Factor completely: 2x3 + 14x2 + 6x + 42

2[(x2 + 3)(x + 7)]

(2x2 + 6)(x + 7)

(x2 + 3)(2x + 14)

2(x3 + 7x2 + 3x + 21) ...?

you would first factor out the 2 and then use the reverse foil method and get the first answer. 2(x^2+3)(x+7)

Correct answer is A.


2x^3 + 14x^2 + 6x + 42 \\2x^2(x+7)+6(x+7) \\(x+7)(2x^2+6) \\(x+7)2(x^2+3)
