Solution for (x/2+1)^2-1=x^2-1 equation: 


x in (-oo:+oo)

(x/2+1)^2-1 = x^2-1 // - x^2-1

(x/2+1)^2-x^2-1+1 = 0

(1/2*x+1)^2-x^2-1+1 = 0

(1/2*x+1)^2-x^2-1+1 = 0

x-3/4*x^2-1+1+1 = 0

x-3/4*x^2+1 = 0

x-3/4*x^2+1 = 0

x-3/4*x^2+1 = 0

DELTA = 1^2-(-3/4*1*4)

DELTA = 4

DELTA > 0

x = (4^(1/2)-1)/(-3/4*2) or x = (-4^(1/2)-1)/(-3/4*2)

x = -2/3 or x = 2

(x+2/3)*(x-2) = 0

(x+2/3)*(x-2) = 0

( x+2/3 )

x+2/3 = 0 // - 2/3

x = -2/3

( x-2 )

x-2 = 0 // + 2

x = 2

x in { -2/3, 2 }
