D( b )
b-2 = 0
b-2 = 0
b-2 = 0
b-2 = 0 // + 2
b = 2
b in (-oo:2) U (2:+oo)
4/(b-2) = 4/12 // - 4/12
4/(b-2)-(4/12) = 0
4/(b-2)-1/3 = 0
(3*4)/(3*(b-2))+(-1*(b-2))/(3*(b-2)) = 0
3*4-1*(b-2) = 0
14-b = 0
(14-b)/(3*(b-2)) = 0
(14-b)/(3*(b-2)) = 0 // * 3*(b-2)
14-b = 0
14-b = 0 // - 14
-b = -14 // * -1
b = 14
b = 14
