X2+a2 =y2+b2= ax
+by =1 then the numerical value of a2 +b2 is=

• this question based on imagination, so put the value of x,y,a,b=1/root 2
  given in que...
  x2+a2=y2+b2=ax+by=1
  now put the value of x,y,a,b=1/root 2
  ((1/root 2))2+((1/root 2))2=((1/root 2))2+((1/root 2))2=(1/root 2)(1/root 2)+(1/root 2)(1/root 2)=1
  condition satisfy then,
  =a2+b2
  =((1/root 2))2+((1/root 2))2
  =1 (Ans)
