Solution for 2S/4x2=38 equation: 


x in (-oo:+oo)

((2*S)/4)*x^2 = 38 // - 38

((2*S)/4)*x^2-38 = 0

1/2*S*x^2 = 38 // : 1/2*S

x^2 = 76*S^-1

x^2 = 76*S^-1 // ^ 1/2

abs(x) = 2*19^(1/2)*S^(-1/2)

x = 2*19^(1/2)*S^(-1/2) or x = -(2*19^(1/2)*S^(-1/2))

x in { 2*19^(1/2)*S^(-1/2), -(2*19^(1/2)*S^(-1/2)) }
