3x(x - 2) - 1 = 3(x + 2)(x + 4) ?
3x(x - 2) - 1 = 3(x + 2)(x + 4) . Porfa alguien q me ayude.
3x(x - 2) - 1 = 3(x + 2)(x + 4) . Porfa alguien q me ayude.
En resumen
3x(x - 2) - 1 = 3(x + 2)(x + 4) 3x² - 6x - 1 = 3(x² + 6x + 8) 3x² - 6x - 1 = 3x² + 18x + 24 - 6x - 1 = 18x + 24 - 1 - 24 = 18x + 6x - 25 = 24x - 25 / 24 = x.
3x(x - 2) - 1 = 3(x + 2)(x + 4)
3x² - 6x - 1 = 3(x² + 6x + 8)
3x² - 6x - 1 = 3x² + 18x + 24 - 6x - 1 = 18x + 24 - 1 - 24 = 18x + 6x - 25 = 24x - 25 / 24 = x.
