- 4x ^ 2 + 8x = 0 me ayudan ?
- 4x ^ 2 + 8x = 0 me ayudan ? 3x ^ 2 - 18 = 0 8x ^ 2 + 7 = 0.
En resumen
- 4x² + 8x = 0 4x( - x + 2) = 0 4x = 0 = > x = 0 / 4 = > x = 0 - x + 2 = 0 = > 2 = x 3x² - 18 = 0 X² = 18 / 3 X² = 6 X = ± √6 8x² + 7 = 0 8X² = - 7 X² = - 7 / 8 X = ±√ - 7 / 8 números imaginarios.
Mejor respuesta
- 4x² + 8x = 0
4x( - x + 2) = 0
4x = 0 = > x = 0 / 4 = > x = 0 - x + 2 = 0 = > 2 = x
3x² - 18 = 0
X² = 18 / 3
X² = 6
X = ± √6
8x² + 7 = 0
8X² = - 7
X² = - 7 / 8
X = ±√ - 7 / 8 números imaginarios.
