2 9.2e-5*x + 0.00024*x + 245831 = 0
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(0.000240000000000000)^2 - 4 * (9.20000000000000e-5) * (245831) = -90.4658079424000
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
x1 = -1.30434782608696 - 51692.1278847679*I
x2 = -1.30434782608696 + 51692.1278847679*I
