El profesor se sorprenderá mucho al ver tu solución correcta😉
128*(x + 12) + 128*(x - 12) = 29*(x - 12)*(x + 12)
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(256)^2 - 4 * (-29) * (4176) = 549952
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
______ 128 4*\/ 8593 x1 = --- - ---------- 29 29
______ 128 4*\/ 8593 x2 = --- + ---------- 29 29
x2 = 128/29 + 4*sqrt(8593)/29
