Answer 1

Wrong again, its C.

Answer 2

prysik, are you just guessing at these?

Answer 3

Sorry,no

Answer 4

@prysik
you are looking for two numbers whose product is 16, and whose sum is -10.
-4 and -4 do not fit the bill (sum=-8).
-2 and -8 have a product of +16, and a sum of -10, that's why C is the correct answer.
