Finding roots of 3rd degree polynomial
WebFind factors for polynomials (3rd degree) by grouping and then solve. Simple and easy explanation by PreMath.com WebExample 1. An example of a polynomial (with degree 3) is: p(x) = 4x 3 − 3x 2 − 25x − 6. The factors of this polynomial are: (x − 3), (4x + 1), and (x + 2) Note there are 3 factors for a degree 3 polynomial. When we multiply those 3 terms in brackets, we'll end up with the polynomial p(x).
