El profesor se sorprenderá mucho al ver tu solución correcta😉
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(-14)^2 - 4 * (5) * (64) = -1084
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)

x2 = 7/5 + sqrt(271)*i/5
x1 = 1.4 + 3.29241552663087*i
x2 = 1.4 - 3.29241552663087*i
x2 = 1.4 - 3.29241552663087*i
