Did You Know...
You can find all roots of a polinomial and find the polinomial coefficients given the roots.

For example.
Lets calculate all roots of the polonomial X^4 - 10X^3 + 35X^2 -50X +24
1 - type : [1 -10 35 -50 24] , type PROOT and press [ENTER]
Result: [1 2 3 4]
2 - using [1 2 3 4] and the comand [PCOEF] [ENTER] you can find the coefficients of the polinomial
For example:[1 -3 1 5] [PCOEF] [ENTER]
4 - result: [ 1 -5 -7 41 -30 ] or X^4 - 5X^3 - 7X^2 + 41X - 30
