Solution for 1/4x^2-2y=5 equation: 


x in (-oo:+oo)

(1/4)*x^2-(2*y) = 5 // - 5

(1/4)*x^2-(2*y)-5 = 0

(1/4)*x^2-2*y-5 = 0

1/4*x^2 = -(-2*y-5) // : 1/4

x^2 = 4*(5-(-2*y))

x^2 = 4*(2*y+5) // ^ 1/2

abs(x) = 2*(2*y+5)^(1/2)

x = 2*(2*y+5)^(1/2) or x = -(2*(2*y+5)^(1/2))

x in { 2*(2*y+5)^(1/2), -(2*(2*y+5)^(1/2)) }
