Question

A polynomial function that has roots 1 and 3 + i. The complex conjugates theorem states that must also be a (blank) root.

Answer 1

Complex roots come in pairs

if you have a root of 3+i  you must have a root of 3-i

Answer 2

Answer:

in Edge: Second question: The factors of the polynomial are (X-1)[X-(3+i)] [X-(3-i)]

in Edge: Third question:  The polynomial function of least degree with a leading coefficient of 1 is:  A= -7  B= 16  C= -10
