x = 0
x in (-oo:0) U (0:+oo)
2/x-((3/2)*x)+1+5 = (5/6)*x+3 // - (5/6)*x+3
2/x-((3/2)*x)-((5/6)*x)-3+1+5 = 0
(-3/2)*x+(-5/6)*x+2/x-3+1+5 = 0
2*x^-1-7/3*x^1+3*x^0 = 0
(3*x^1-7/3*x^2+2*x^0)/(x^1) = 0 // * x^2
x^1*(3*x^1-7/3*x^2+2*x^0) = 0
x^1
(-7/3)*x^2+3*x+2 = 0
(-7/3)*x^2+3*x+2 = 0
DELTA = 3^2-(2*4*(-7/3))
DELTA = 83/3
DELTA > 0
x = ((83/3)^(1/2)-3)/(2*(-7/3)) or x = (-(83/3)^(1/2)-3)/(2*(-7/3))
x = -3/14*((83/3)^(1/2)-3) or x = 3/14*((83/3)^(1/2)+3)
x in { -3/14*((83/3)^(1/2)-3), 3/14*((83/3)^(1/2)+3)}
x in { -3/14*((83/3)^(1/2)-3), 3/14*((83/3)^(1/2)+3) }
