The maximum value of the function
$$f\left( x \right) = 2{x^3} - 15{x^2} + 36x - 48$$ on the set
$${\rm A} = \left\{ {x|{x^2} + 20 \le 9x} \right\}$$ is

Let $$p(x)$$ be a polynomial of degree $$4$$ having extremum at
$$x = 1,2$$ and $$\mathop {\lim }\limits_{x \to 0} \left( {1 + {{p\left( x \right)} \over {{x^2}}}} \right) = 2$$.

Then the value of $$p (2)$$ is
