2xelevado al cubo - 7x = - 3Ecuacion?
2xelevado al cubo - 7x = - 3 Ecuacion.
2xelevado al cubo - 7x = - 3 Ecuacion.
En resumen
2 ^ 3 - 7x = 3 8 - 7x = - 3 - 7x = - 3 - 8 - 7x = - 11 x = - 11 : ( - 7) x! = 1, 57.
2 ^ 3 - 7x = 3
8 - 7x = - 3 - 7x = - 3 - 8 - 7x = - 11
x = - 11 : ( - 7)
x!
= 1, 57.
X ^ 2 . (x + 1) x ^ 3 + x ^ 2 . . .
x (x - 1)(x + 2) = 0 x = 0 x - 1 = 0 x = 1 x + 2 = 0 x = - 2.
Ahi te va la solucion.
