El profesor se sorprenderá mucho al ver tu solución correcta😉
a*v^2 + b*v + c = 0
D = b^2 - 4 * a * c =
(2)^2 - 4 * (1) * (-35) = 144
v1 = (-b + sqrt(D)) / (2*a)
v2 = (-b - sqrt(D)) / (2*a)
log(5) x1 = ------ log(7)
pi*I x2 = 1 + ------ log(7)
x2 = 1 + i*pi/log(7)
suma
log(5) pi*I ------ + 1 + ------ log(7) log(7)
=
log(5) pi*I 1 + ------ + ------ log(7) log(7)
producto
log(5) / pi*I \ ------*|1 + ------| log(7) \ log(7)/
=
(pi*I + log(7))*log(5) ---------------------- 2 log (7)
(pi*i + log(7))*log(5)/log(7)^2
x1 = 0.827087475346916
x2 = 1.0 + 1.61445925708078*i
x2 = 1.0 + 1.61445925708078*i
