Nothing. The prime factorization of 14 is 1,2,7,14. From those options none will multiply to -14 and add to -12.
38
-1
-8
if you multiply them it adds up to 516
-13
The numbers are 3 and -12
The numbers are -2 and -12 because -2 times -12 = 24 and -2+(-12) = -14
-14
No integers. It works the other way around. 6 and 2 multiply to 12, add to 8.
-13
The two numbers that add up to -18 and multiply to -24 are -12 and -6. When you add them together, -12 + -6 equals -18. When you multiply them, -12 * -6 equals 72, but since we need the product to be -24, the correct pairs are -12 and -6.
