If the expression above has 3 real roots r1,r2,r3{ r }_{ 1 },{ r }_{ 2 },{ r }_{ 3 }r1,r2,r3 in an arithmetic progression having common difference 1 then find the value of
r12+r23+r32.{ { r }_{ 1 } }^{ 2 }+{ { r }_{ 2 } }^{ 3 }+{ { r }_{ 3 } }^{ 2 }.r12+r23+r32.
Note: The exponents in the expression are indeed 2,3,22, 3, 2 2,3,2.
