Solution for (x^2)/4-4y^2=1 equation: 


x in (-oo:+oo)

(x^2)/4-(4*y^2) = 1 // - 1

(x^2)/4-(4*y^2)-1 = 0

(x^2)/4-4*y^2-1 = 0

1/4*x^2 = -(-4*y^2-1) // : 1/4

x^2 = 4*(1-(-4*y^2))

x^2 = 4*(4*y^2+1) // ^ 1/2

abs(x) = 2*(4*y^2+1)^(1/2)

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

x in { 2*(4*y^2+1)^(1/2), -(2*(4*y^2+1)^(1/2)) }
