(14*x^2)/g-2*g^2-(6*g)+5 = 0
(14*x^2)/g-2*g^2-6*g+5 = 0
14*g^-1*x^2 = -(5-2*g^2-6*g) // : 14*g^-1
x^2 = (-1/14)*g*(5-2*g^2-6*g)
x^2 = -1/14*g*(5-2*g^2-6*g) // ^ 1/2
abs(x) = (-1/14)^(1/2)*g^(1/2)*(5-2*g^2-6*g)^(1/2)
x = (-1/14)^(1/2)*g^(1/2)*(5-2*g^2-6*g)^(1/2) or x = -((-1/14)^(1/2)*g^(1/2)*(5-2*g^2-6*g)^(1/2))
x in { (-1/14)^(1/2)*g^(1/2)*(5-2*g^2-6*g)^(1/2), -((-1/14)^(1/2)*g^(1/2)*(5-2*g^2-6*g)^(1/2)) }
