Apolynomial of degree n can have at the most n zeroes.....

For convience of understanding (i)Let n = 5 , in this case the polynomial can have 5 zeros or less than 5 zeroes i.e 4,3,2,1number of zeroes. In this case the polynomial can be 9x^{5} + 5a^{4} + 10y^{3 }+ 12z^{2 }+ 8k^{1 }+ 25s^{0}

(ii) Let n =2, in this case this is a quadatic polynomial with 2 zeros or less than 2 zeroes i.e 1 zero. In this case the polynomial can be 26x^{2} + 45y +87

Hope this helped you
