x = 0
x in (-oo:0) U (0:+oo)
10/x = (11/3)*x-3 // - (11/3)*x-3
10/x-((11/3)*x)+3 = 0
(-11/3)*x+10/x+3 = 0
10*x^-1-11/3*x^1+3*x^0 = 0
(3*x^1-11/3*x^2+10*x^0)/(x^1) = 0 // * x^2
x^1*(3*x^1-11/3*x^2+10*x^0) = 0
x^1
(-11/3)*x^2+3*x+10 = 0
(-11/3)*x^2+3*x+10 = 0
DELTA = 3^2-(4*10*(-11/3))
DELTA = 467/3
DELTA > 0
x = ((467/3)^(1/2)-3)/(2*(-11/3)) or x = (-(467/3)^(1/2)-3)/(2*(-11/3))
x = -3/22*((467/3)^(1/2)-3) or x = 3/22*((467/3)^(1/2)+3)
x in { -3/22*((467/3)^(1/2)-3), 3/22*((467/3)^(1/2)+3)}
x in { -3/22*((467/3)^(1/2)-3), 3/22*((467/3)^(1/2)+3) }
