sketch the graph of polynomial function
l(x)=(x - 3)^2 (x + 4)^3
m(x)=14 + 21x - 2x^2 - 3x^3
..
l(x)=(x - 3)^2 (x + 4)^3
This function has 5 real roots, x=3 (multiplicity 2) and x=-4(multiplicity 3),
as shown by the following graph.

..
m(x)=14 + 21x - 2x^2 - 3x^3
m(x)=(7-x^2)(3x^2+2)
This function has 2 imaginary roots and 2 real roots at x=±√7, as shown by the following graph
