D( v )
v-2 = 0
v-2 = 0
v-2 = 0
v-2 = 0 // + 2
v = 2
v in (-oo:2) U (2:+oo)
-6/(v-2) = 4*(5*v-10)+1 // - 4*(5*v-10)+1
-6/(v-2)-(4*(5*v-10))-1 = 0
-6/(v-2)-4*(5*v-10)-1 = 0
(-4*(5*v-10)*(v-2))/(v-2)-6/(v-2)+(-1*(v-2))/(v-2) = 0
-4*(5*v-10)*(v-2)-1*(v-2)-6 = 0
80*v-20*v^2-v-86+2 = 0
79*v-20*v^2-84 = 0
79*v-20*v^2-84 = 0
79*v-20*v^2-84 = 0
DELTA = 79^2-(-84*(-20)*4)
DELTA = -479
DELTA < 0
1 = 0
1/(v-2) = 0
1/(v-2) = 0 // * v-2
1 = 0
v belongs to the empty set
