x + y = 1.....x = 1 - y
x * y = 0.09

y(1 - y) = 0.09
y - y^2 = 0.09....re-arrange
y^2 - y + 0.09 = 0
(y - 0.9)(y - 0.1) = 0

y - 0.9 = 0      x + y = 1
y = 0.9           x + 0.9 = 1
                      x = 0.1

y - 0.1            x + y = 1
y = 0.1           x + 0.1 = 1
                      x = 0.9

so ur 2 numbers are : 0.1 and 0.9
