-2 and 18
-6 and 6
3 and -12
4 and -9

Answer 1

the correct answer is

-2 and 18

4 and -9

Answer 2

-2 and 18....both factors of -36...-2 = 18/2 - 11...-2 = 9 - 11....-2 = -2
this is one

-6 and 6...both factors of -36....-6 = 6/2 - 11....-6 = 3 - 11....-6 = - 8
this is not one

3 and -12...both factors of -36...3 = -12/2 - 11....3 = -6 - 11...3 = - 17
this is not one

4 and -9....both factors of -36...-9 = 4/2 - 11...-9 = 2 - 11...-9 = -9
this is one
