Steps for solution
 +
 +
step 1:  * Understanding the  problem first.
 +
    * Recalling the indentities
 +
 +
step  2 :  * consider the condition and squaring on both side
 +
    * simplify to get the value
 +
 +
step 3:    *  consider  LHS
 +
    *  multiply the expression
 +
    *  substitute the value
 +
    *  simlpify the equqtion
 +
 +
 +
solution for the problem
 +
 +
consider  x+y=a
 +
=
 +
substitute x+y =a and xy=b
 +
then we get
 +
                    ------->(1)
 +
consider xy=b squaring on both side
 +
then we get =------->(2)
 +
 +
consider LHS=
 +
=(1+)+(1+)
 +
=1+
 +
= 1+ from eqn 1 & 2
 +
=

=

        LHS = RHS=============
