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=============
