Factorize the polynomial \( p(x)=x^{3}-3 x^{2}-9 x-5 \) Hint: \( p(5)=0 \)

(10) If \( f(x)=2 x+k \) is the inverse function of \( g(x)=m x+3 \), then \( m \times k=-12 \) \( \begin{array}{llll}\text { (a) } 3 & \text { (b) } 6 & \text { (c) }-12 & \text { (d) }-3\end{array} \)

A) \( a^{2}-25=(a-5)(a+5) \)

9. Malced the subject of the relation \( w=M \sqrt{\frac{\left(D^{2}+d^{2}\right)}{2 d^{2}}} \)

II. \( (3+c)^{2} \)
