I forgot to give the given numbers. -sqrt10 and 8sqrt10
x = -sqrt(10), x = 8sqrt(10).
x + sqrt(10) = 0,
x - 8sqrt(10) = 0,
(x + sqrt(10) (x - 8sqrt(10) = 0,
x^2 - 8sqrt(10)x + sqrt(10)x - 80 = 0,
Eq: x^2 - 7sqrt(10)x - 80 = 0.
x + sqrt(10) = 0,
x - 8sqrt(10) = 0,
(x + sqrt(10) (x - 8sqrt(10) = 0,
x^2 - 8sqrt(10)x + sqrt(10)x - 80 = 0,
Eq: x^2 - 7sqrt(10)x - 80 = 0.
