There are no real numbers that will answer this question, just imaginary numbers.
The imaginary numbers are 1+sqrt(-2) and 1-sqrt(-2), which we normally write as 1+2i and 1-2i where i stands for the sort of (-1)
(1+2i) + (1-2i) =2
(1+2i) * (1-2i) = 3 (note * stands for multiply)
3
The numbers are 3 and 25
-11
5
There are many possible answers. One such of the following: {3, 20, and 34 lots of -1}. Another is {-15, 4}
25
-1
3
The numbers are 2 and -5
-5
-7
-3
They are: 3+2 = 5 and 3^2 = 9
3
4
-2 and -3 -2 + (-3) = -5 -2 x -3 = 6
-3
