Proof of thisstatement has been given by Dickson ( 1 ) in this research on irreducibility , unless itis mentioned , we shall be dealing with exclusively with reciprocal polynomials of the 2first kind of even degree having the property that f ( 1 ) 0 , (from equation ( 2 ) ofthe paper, it can be proved that every reciprocal equation of first kind with odd degreemust have - 1 as a root )Supposef (x) = f1 ( x ) f 2( x ) .
