a^2*b^2+a^2+b^2=259
b^2*c^2+b^2+c^2=1299
c^2*a^2+c^2+a^2=499
then find b=?	Choose the correct option:  A) 2  B) 3  C) 4  D) 5  E) 6
adding 1 to all equqtions.,we get them modified to the following form   (a^2+1)(b^2+1)=260   (b^2+1)(c^2+1)=1300   (c^2+1)(a^2+1)=500   by corresponding mul and div we get a=3,b=5,c=7   ANSWER:5
