El profesor se sorprenderá mucho al ver tu solución correcta😉
2 (2*x + 5)*(x - 6) + 2*(3*x + 2)*(3*x - 2) = 5*(2*x + 1) + 11
(2*x+5)*(x-6)+2*(3*x+2)*(3*x-2) = 5*(2*x+1)^2+11
- 30 - 7*x + 2*x^2 + (2*(3*x + 2))*(3*x - 2) = 5*(2*x+1)^2+11
- 30 - 7*x + 2*x^2 + - 8 + 18*x^2 = 5*(2*x+1)^2+11
(2*x+5)*(x-6)+2*(3*x+2)*(3*x-2) = 5 + 20*x + 20*x^2 + 11
-54 - 27*x = 0
x = 54 / (-27)
