D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
5/x = (10/3)*x+4 // - (10/3)*x+4
5/x-((10/3)*x)-4 = 0
(-10/3)*x+5/x-4 = 0
5*x^-1-10/3*x^1-4*x^0 = 0
(5*x^0-10/3*x^2-4*x^1)/(x^1) = 0 // * x^2
x^1*(5*x^0-10/3*x^2-4*x^1) = 0
x^1
(-10/3)*x^2-4*x+5 = 0
(-10/3)*x^2-4*x+5 = 0
DELTA = (-4)^2-(4*5*(-10/3))
DELTA = 248/3
DELTA > 0
x = ((248/3)^(1/2)+4)/(2*(-10/3)) or x = (4-(248/3)^(1/2))/(2*(-10/3))
x = -3/20*((248/3)^(1/2)+4) or x = -3/20*(4-(248/3)^(1/2))
x in { -3/20*((248/3)^(1/2)+4), -3/20*(4-(248/3)^(1/2))}
x in { -3/20*((248/3)^(1/2)+4), -3/20*(4-(248/3)^(1/2)) }
