All possible roots of polynomial with integral coefficients can be identified by "RATIONAL ROOT TEST"according to rational root test if a plynomial ltbr. a_(n)p^(n)+a_(n-1)p^(n-1)q+a_(n-2)p^(n-2)q^(2)+…..+a_(2)p^(2)q^(n-2)+a_(1)pq^(n-1)+a_(0)q^(n)=0 Every term in above equation except possible the last one is divisible by p hence p should also divide a_(0)q^(n), since q and p are relatively prime p must divide a_(0). Similarly q also divides a_(n). Now consider an equation 6x^(5)-19x^(4)-9x^(3)-16x^(2)+9x-1=0 and answer the following questions Q. Sum of real roots of equation will be
