Question

X(x+6)-2x-6=(x-4)(x-5)

Answer 1

Respuesta:

-0.8571428571428571 = x

Explicación paso a paso:

$x^2$ + 6x - 2x - 6 = $x^2$ - 5x -4x + 20x

$x^2$ + 4x - 6 = $x^2$ - 9x + 20 x

$x^2$ + 4x -6 = $x^2$ + 11x

$x^2$ - $x^2$ + 4x = 11x + 6

4x = 11x + 6

-6 = 11x - 4x

-6 = 7x

-0.8571428571428571 = x
