Which of the following is the complete list of roots for polynomial function f(x)=(x^2+6x+8)(x^2+6x+13)?

a)-3+2i,-3-2i

b)-2,-4

c)-2,-4,-3+2i,-3-2i

d)-2,-4,-3+2i,3+2i

Equaling the function to zero we have:

For the first parenthesis we have:

Therefore the roots are:

For the second parenthesis we have:

By completing squares we have:

Therefore the roots are:

The following is the complete list of roots for polynomial function:

C) -2, -4, -3 + 2i, -3-2i

The complete roots of the function are .Option (C) is correct.

Further explanation:

The Fundamental Theorem of Algebra states that the polynomial has n roots if the degree of the polynomial is n.

The polynomial function has roots or zeroes.

Given:

The function is

Explanation:

To obtain the roots of the polynomial function substitute for
