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
