Imaginary Roots Of A Polynomial Function. By yang kuang elleyne kase. In pre calculus and in calculus certain polynomial functions have non real roots in addition to real roots and some of the more complicated functions have all imaginary roots.
Solve the equation x 8x 24x 32x 20 0 if one of its roots is 3 i. Hence the roots are 2 i 3 2 i 3 2 i 2 i. Let us take an example of the polynomial p x of degree 1 as given below.
The degree is 5 so there are 5 roots in total.
Thus in order to determine the roots of polynomial p x we have to find the value of x for which p x 0. Let us see another example of the topic how to find complex roots of a 4th degree polynomial. Total number of roots. Thus in order to determine the roots of polynomial p x we have to find the value of x for which p x 0.
