4x al cuadrado + x = 0x al cuadrado + 7x = 05x al cuadrado - 2x = 0?
4x al cuadrado + x = 0 x al cuadrado + 7x = 0 5x al cuadrado - 2x = 0.
4x al cuadrado + x = 0 x al cuadrado + 7x = 0 5x al cuadrado - 2x = 0.
En resumen
4x ^ 2 + x = 0x. (4x + 1) = 0 4x + 1 = 0 4x = - 1 x = - 1 / 4 x1 = 0 x2 = - 1 / 4 x ^ 2 + 7x = 0x. (x + 7) = 0 x + 7 = 0 x = - 7 x1 = 0 x2 = - 7 5x ^ 2 - 2x = 0x. (5x - 2) = 0 5x - 2 = 0 5x = 2 x = 2 / 5 x1 = 0 x2 = 2 / 5.
4x ^ 2 + x = 0x.
(4x + 1) = 0 4x + 1 = 0 4x = - 1 x = - 1 / 4 x1 = 0 x2 = - 1 / 4
x ^ 2 + 7x = 0x.
(x + 7) = 0 x + 7 = 0 x = - 7 x1 = 0 x2 = - 7
5x ^ 2 - 2x = 0x.
(5x - 2) = 0 5x - 2 = 0 5x = 2 x = 2 / 5 x1 = 0 x2 = 2 / 5.
