If $P(x)=3{{x}^{3}}+11{{x}^{2}}-4x+5$and $Q(x)=x+7$, find $P(x) imes Q(x)$, $P(2) imes Q(2)$, the

Question

If $P(x)=3{{x}^{3}}+11{{x}^{2}}-4x+5$and $Q(x)=x+7$, find $P(x)	imes Q(x)$, $P(2)	imes Q(2)$, the relationship between the degrees of $P(x),Q(x)$ and $P(x)	imes Q(x)$

Accepted Answer

(i) $3x^4 + 32x^3 + 73x^2 - 23x + 35$; (ii) $585$; (iii) Degree of $P(x)$ + Degree of $Q(x)$ = Degree of $P(x) \times Q(x)$
