Use number keyboard on the bottom of the screen to input coefficients of polynomial or tap on menu bar above the keyboard to change the leading degree of the polynomial.

Input polynomials with form: p(x) = q(x) . (x - x1)...

This input form is useful when one or more roots of the polynomial are known:

p(x) = q(x).(x-x1)...
