El profesor se sorprenderá mucho al ver tu solución correcta😉
log(4) / 2 \ 2 ------*\x - 2*x - 2/ = x - 2*x - 3 10
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(2 - 2*log(2)/5)^2 - 4 * (-1 + log(2)/5) * (3 - 2*log(2)/5) = (2 - 2*log(2)/5)^2 - (-4 + 4*log(2)/5)*(3 - 2*log(2)/5)
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
