El profesor se sorprenderá mucho al ver tu solución correcta😉
___ ___ \/ x + 5 + \/ 2 - x = 0
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(11 + 2*sqrt(2))^2 - 4 * (-1) * (-27 - 10*sqrt(2)) = -108 + (11 + 2*sqrt(2))^2 - 40*sqrt(2)
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
______________ / ___ 11 ___ \/ 21 + 4*\/ 2 x1 = -- + \/ 2 + ----------------- 2 2
x1 = sqrt(2) + sqrt(4*sqrt(2) + 21)/2 + 11/2
suma
______________ / ___ 11 ___ \/ 21 + 4*\/ 2 -- + \/ 2 + ----------------- 2 2
=

producto
______________ / ___ 11 ___ \/ 21 + 4*\/ 2 -- + \/ 2 + ----------------- 2 2
=
