$3$

$2$

${16 x}^{4} - {6 x}^{3} - {5 x}^{2} + 7 x - 6$

${6 x}^{3} + {6 x}^{2} - 14 x + 17$

$4$

Add the following polynomials and find the degree of the resultant polynomial.

S.No	Polynomials	Sum of polynomials	Degree of the resultant polynomial
(i)	$p(x) = 6x^2 - 7x + 2$ $q(x) = 6x^3 - 7x + 15$
(ii)	$h(x) = 7x^3 - 6x + 1$ $f(x) = 7x^2+ 17x - 9$
(iii)	$f(x) = 16x^4 - 5x^2 + 9$ $g(x) = -6x^3 + 7x - 15$
