-4 x 3 = -12, and -4 + 3 = -1.

===================================

X + Y = -1

XY = -12

You want two numbers, X and Y. Multiplied together they will equal 12; if one of them is negative they will equal -12. They are one apart from each other, and if the larger one is negative their sum will be -1.

12 = 2 x 2 x 3, and the factors 4 and 3 are one apart from each other. If you make the larger one negative, it will fit both equations above.

The complexity of this question lies in its having a negative factor; if you ignore that at first, the answer is easy to see.

To solve it algebraically, you end up with: -X2 - X + 12 = 0; then you have to solve the quadratic.
