The average of two numbers is 41.375 and their product is 1668 what are their numbers?

A) x * y = 1668

B) (x + y) / 2 = 41.375

B) 2x + 2y = 82.75

x = 1668/y

2 * (1668/y) + 2y = 82.75

Multiplying both sides by "y"

3336 + 2y^2 = 82.75y

2y^2 - 82.75y + 3336 = 0

Used an online quadratic equation calculator

x1 = 20.688 plus 35.214 i

x2 = 20.688 minus 35.214 i

I don't know if I did that correctly.
