### 5.25.23 Random polynomial : randpoly randPoly

randpoly (or randPoly) takes two arguments: the name of a variable (by default x) and an integer n (the order of the arguments is not important).
randpoly returns a polynomial with respect to the variable given argument (or x if none was provided), of degree the second argument, having as coefficients random integers evenly distributed on -99..+99.
Input :

randpoly(t,4)

Output for example:

-8*t`^`4-87*t`^`3-52*t`^`2+94*t+80

Input :

randpoly(4)

Output for example:

70*x`^`4-46*x`^`3-7*x`^`2-24*x+52

Input :

randpoly(4,u)

Output for example:

2*u`^`4+33*u`^`3-6*u`^`2-92*u-12
