### 2.24.23 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`
