1)
4/(V6-2) =4/(V6-2) *(V6+2)/(V6+2) =4(6+2)/(6-4) =4(V6+2)/2 =2(V6+2)
2)
((6V3-1)/(V3+1)(V3-1) =(6V3-1)/(3-2) =6V3-1
3)
V2/(3+V2) =V2/(3+V2) *(3-V2)/(3-V2) =V2(3-V2) =3V2-2
4)
2/(V3-1) *(V3+1)/(V3+1) =2(V3+1)/2 =V3+1
5)
(V5+1)/(V5-1) =(V5+1/(V5-1) *(V5+1)/(V5+1) =((V5+1)^2/4 =(5+2V5+1)/4 =
= (2V5+6)/4 =2(V5+3)/4 =(V5+3)/2
