Question

(2x-1)^2 -4 = 6x -(2x+1)^2

Answer 1

Respuesta:

Explicación paso a paso:

$(2x-1)^{2} -4=6x-(2x+1)^{2}$

$4x^{2} -4x + 1- 4 = 6x - (4x^{2} +4x+1)$

$4x^{2} -4x -3 = 6x - 4x^{2} -4x-1$

$4x^{2} +4x^{2} -4x-6x+4x-3+1=0$

$8x^{2}-6x -2=0$

$(8x+2)(x-1)=0$

$8x+2=0\\8x=-2\\x=(-2/8)$

$x-1=0\\x=1$
