x²(x+2) + 7x(x+2) + 6(x+2) = 0.

Factor out x+2:
(x+2)(x² + 7x + 6) = 0

Factor the quadratic in red:
(x+2)(x+6)(x+1) = 0

Option for x:
x=-2, x=-6, x==-1.
Thus, the product of all the solutions = (-2)(-6)(-1) = -12.

The correct answer is B.

We first factor the common (x + 2) from the left side. We have:

(x + 2)(x^2 + 7x + 6) = 0

Now, we can factor the quadratic x^2 + 7x + 6:

(x + 2)(x + 6)(x + 1) = 0

The three possible values for x are x = -2 or -6 or -1, for a product of -12.

Answer: B
