Solution for (3b-3)/(b^2-2b) equation: 


D( b )

b^2-(2*b) = 0

b^2-(2*b) = 0

b^2-(2*b) = 0

b^2-2*b = 0

b^2-2*b = 0

DELTA = (-2)^2-(0*1*4)

DELTA = 4

DELTA > 0

b = (4^(1/2)+2)/(1*2) or b = (2-4^(1/2))/(1*2)

b = 2 or b = 0

b in (-oo:0) U (0:2) U (2:+oo)

(3*b-3)/(b^2-(2*b)) = 0

(3*b-3)/(b^2-2*b) = 0

b^2-2*b = 0

b*(b-2) = 0

b-2 = 0 // + 2

b = 2

b*(b-2) = 0

(3*b-3)/(b*(b-2)) = 0

3*b-3 = 0 // + 3

3*b = 3 // : 3

b = 3/3

b = 1

b = 1
