What is the product in simplest form? state any restrictions of the variable.

(x^2 + 5x + 6)/(x+4) * (x^2 + x - 12)/(x^2 + x - 2)

(x+3)(x-3)/x-1, x not equal to -2, x not equal to -4
(x+3)(x-3)/(x-1)(x+2), x not equal to -2, x not equal to -4, x not equal to 1
(x+3)(x-3)/(x-1)(x+2), x not equal to -2, x not equal to -4
(x+3)(x-3)/(x-1), x not equal to -2, x not equal to -4, x not equal to 1

The product in simplest form is (x+3)(x-3)/(x-1), with the restrictions of x not equal to -2, -4, and 1.
