Answer variants:

{6 x}^{4} + {7 x}^{3} - {56 x}^{2} - 63 x + 18

\(4\)

\(3\)

{105 x}^{2} - 33 x - 18

\(2\)

{30 x}^{3} - {77 x}^{2} + 54 x - 7

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

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