Answer:
 18 and -2
Step-by-step explanation:
Let x = 1st no.
y = 2nd no.
(1)    x + y = 16            (2)     xy = -36
            y = 16 - x                 x(16 - x) = -36
                                            
                                            (x - 18)(x + 2) = 0
                                                x = 18   or x = -2
           y = 16 - 18 = -2
          y = 16 -(- 2) = 16 + 2 - 18
The two numbers are 18 and -2
