Solution for (7/4x^2+4X)+(1/X-2) equation: 


x in (-oo:+oo)

4*X+1/X+(7/4)*x^2-2 = 0

7/4*x^2 = -(4*X+X^-1-2) // : 7/4

x^2 = 4/7*(2-(4*X)-X^-1)

x^2 = 4/7*(2-4*X-X^-1) // ^ 1/2

abs(x) = (4/7)^(1/2)*(2-4*X-X^-1)^(1/2)

x = (4/7)^(1/2)*(2-4*X-X^-1)^(1/2) or x = -((4/7)^(1/2)*(2-4*X-X^-1)^(1/2))

x in { (4/7)^(1/2)*(2-4*X-X^-1)^(1/2), -((4/7)^(1/2)*(2-4*X-X^-1)^(1/2)) }
