    FAQ

    What steps does the quadratic mode display?

    It records the discriminant, substitution into the quadratic formula, optional square-root simplification, vertex calculation, and the resulting factorization so you can follow every transformation.

    How does polynomial mode handle degree 3?

    The solver generates rational root candidates from the factors of the constant term divided by the factors of the leading coefficient, tests them with synthetic division, then solves the remaining quadratic or states that no rational root exists.
