4 4 ________ _______ \/ x + 15 + \/ 1 - x = 2
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(28)^2 - 4 * (2) * (224) = -1008
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
___ x1 = -7 - 3*I*\/ 7
___ x2 = -7 + 3*I*\/ 7
x2 = -7 + 3*sqrt(7)*i
suma
___ ___ -7 - 3*I*\/ 7 + -7 + 3*I*\/ 7
=
-14

x1 = -7.0 - 7.93725393319377*i
x2 = -7.0 + 7.93725393319377*i
x2 = -7.0 + 7.93725393319377*i
