Hello from MrBillDoesMath!

Answer:

1 - i sqrt(11) , 1 + i sqrt(11)  

Discussion:

Translating the Question into mathematical symbols:

x * y = 12     (*)

x + y = 2      (**)

From (**),  y  = 2 - x. Substitute this value in (*)

x * y = x * (2-x) = 12     =>

2x - x^2 = 12               => add x^2, subtract 2x from both sides

0 =  x^2  -2x + 12    

Solving using the quadratic formula gives

x = 1 - i sqrt(11)

and

y = 1 + i sqrt(11)

Thank you,

MrB
