Factor completely. If the polynomial cannot be factored say it is prime.

1) 15x^3 + 19x^2 + 6x

A) (3x^2 +2)(5x+3)

B) x(3x+2)(5x+3)

C) x^2(3x+2)(5x+3)

D) x(5x+2)(3x+3)

E) Prime

I chose E) Prime.

2) 2x^2 - 14x - 6x + 42

A) 2(x+7)(x+3)

B) (x+7)(2x-6)

C) 2(x-7)(x-3)

D) (x-7)(x-3)

E) Prime

I know that this is 2x^2 - 20 + 42 when you combine the 14x and 6x so I chose answer E) Prime but I am not sure for this one.
