Third Case:
If ?? = ?? = ?? = ?? then,
?? ?? ??
a = bm , c = dm , e = fm
Example 1:
if ?? = ?? prove that
?? ??
? ??-?? = ??-?? ? ??+?? = ??+??
?? ?? ?? ??
a=bm , c=dm
1- LHS = ????-?? = ??( ??-?? ) =???-???
???? ????
RHS = ????-?? = ??( ??-?? ) =???-???
???? ????
LHS = RHS
2- LHS = ????+?? = ??( ??+?? ) =???+???
???? ????
RHS = ????+?? = ??( ??+?? ) =???+???
???? ????
LHS = RHS
