Math Help

I need a Math pro to help me with this problem.

Let (X) = d.efg and let (Y) = h.ijk

X + Y = 12.558 and X times Y = 36.929441

Hint, solve for (Y) using the standard quadratic equation and for the +or- before the square root section in the numerator, use the +

Is there anyone out there who can do this for me?

25 fg for the 1st winner.

X = 36.929441/Y

36.929441/Y + Y = 12.558

Y^2 - 12.558*Y + 36.929441 = 0

Y = 12.558/2 + sqrt((12.558/2)^2 - 36.929441)

Y = 7.859

X = 4.699
