0.766, 0.632), (-0.766, -0.632).

Generating polynomial coefficients given the polynomial's roots

Suppose you want to generate the polynomial whose roots are the numbers

[1, 5, -2, 4]. To use the calculator for this purpose, follow these steps:

Select Solve poly…

Enter vector of roots

Solve for coefficients

Press

to return to stack, the coefficients will be shown in the stack.

Press

to trigger the line editor to see all the coefficients.
