Polynomial's calculator
    Examples -3*4/(5+1) 1600/(1-(1+1/4)^2) x2-1 = 0 Factor(x^3 +x^2 -x -1) Roots(x8-1) Poly(-1,2) x+1 @x=3 x+y @x=2@y=1 A^-1 @A=2;0|0;1 y=x2-1@y={0;2;3}
Note 1: if you wish to find the ROOTS of a polynomial you must equal the equation to ZERO. For example, write x^2-1= 0 and DO NOT just write x^2-1. Alternatively, enter: roots(x^2-1)
Note 2: To find a polynomial given the roots (for example if the roots are -1,i,-i) enter POLY(-1;i;-i)
