Graph factored polynomial from roots
WebMay 2, 2024 · Solution. We start by graphing the polynomial f ( x) = x 3 − 7 x 2 + 14 x − 8. The graph suggests that the roots are at x = 1, x = 2, and x = 4. This may easily be … WebOnce students get the factored form, they will be able to match polynomial graphs based on the roots they have. Methods of factoring include basic trinomial (a=1), a > 1, grouping, differences of two squares. Methods of solving also includes the quadratic formula and/or completing the square. Imaginary roots in a polynomial graph are in
