× +11× +24= 0
2× + 11× + 24= 0
13×= - 24
× = - 24 /13
×=1.8
espero que te ayude, dame coronita
Hola! :3
Factorizamos por aspa simple:
x² + 11x + 24
↓ ↓
x +8
x +3
Entonces:
x² + 11x + 24 = (x + 8)(x + 3)
Comprobamos sabiendo que:
(x + a)(x + b) = x² + (a + b)x + ab
Reemplazamos:
(x + 8)(x + 3) = x² + (8 + 3)x + (8)(3)
(x + 8)(x + 3) = x² + 11x + 24
Ahora determinamos los valores de "x":
(x + 8)(x + 3) = 0
x₁ + 8 = 0
x₁ = -8
x₂ + 3 = 0
x₂ = -3
x = { -8; -3}
Espero haberte ayudado :D
