Find all the zeros of the polynomial function p(x) x^4-4x^3 -5x^2+38x- 30

The zeros of the polynomial function are 1, -3, 3+i and 3-i.

Step-by-step explanation:

The given function is

We can find a zero of the given function by hit and trial method.

Substitute x=1 in the given function.

The value of function is 0 at x=1 it means (x-1) is a factor of given function.

Substitute x=-3 in the given function.

The value of function is 0 at x=-3 it means (x+3) is a factor of given function.

Divide the given function by , to get remaining factors.

So, the factor form of given function is

Quadratic formula: If a quadratic equation is , then

Using quadratic formula find the zeroes of .

Therefore the zeros of the polynomial function are 1, -3, 3+i and 3-i.
