El profesor se sorprenderá mucho al ver tu solución correcta😉
2 (2*x - 7)*(x + 1) + 3*(4*x - 1)*(4*x + 1) = 2*(5*x - 2) - 53
(2*x-7)*(x+1)+3*(4*x-1)*(4*x+1) = 2*(5*x-2)^2-53
- 7 - 5*x + 2*x^2 + (3*(4*x - 1))*(4*x + 1) = 2*(5*x-2)^2-53
- 7 - 5*x + 2*x^2 + - 3 + 48*x^2 = 2*(5*x-2)^2-53
(2*x-7)*(x+1)+3*(4*x-1)*(4*x+1) = 8 - 40*x + 50*x^2 - 53
35 + 35*x = 0
x = -35 / (35)
