We solved each of these by first factoring the polynomial and then using the zero factor property on the factored form. This same principle applies to polynomials of degree four and higher. The polynomial is of degree two, so there will be two roots (zeroes). form a polynomial function whose real zeros and degree are given. The roots of a polynomial are exactly the same as the zeros of the corresponding polynomial function. We can also identify the sign of the leading coefficient by observing This can be seen as a form of polynomial interpolation with harmonic base functions, see trigonometric interpolation and trigonometric polynomial. Technically, the a constant can't be zero if the equation is to be called a "fourth degree polynomial" but this brings up an interesting point: a lower degree polynomial is only a higher degree polynomial with all the higher order terms having multiplicative constants equal to zero. 7c; CC. 5). b) Degree 5 ; zeros 1, multiplicity 3; 1+i - Slader 38. f ( ) =3 3 −2 +8x 5 2.
