D( x )
x-3 = 0
x-3 = 0
x-3 = 0
x-3 = 0 // + 3
x = 3
x in (-oo:3) U (3:+oo)
y = (5*x-11)/(x-3) // - (5*x-11)/(x-3)
y-((5*x-11)/(x-3)) = 0
(-1*(5*x-11))/(x-3)+y = 0
(-1*(5*x-11))/(x-3)+(y*(x-3))/(x-3) = 0
y*(x-3)-1*(5*x-11) = 0
x*y-5*x-3*y+11 = 0
(x*y-5*x-3*y+11)/(x-3) = 0
(x*y-5*x-3*y+11)/(x-3) = 0 // * x-3
x*y-5*x-3*y+11 = 0
x*y-3*y+11 = 0 // - 11-3*y
x*y = -(11-3*y) // : y
x = (-(11-3*y))/y
x = -(y^-1*(11-3*y))
x = -(y^-1*(11-3*y))
