Question

Form a polynomial f(x) with real coefficients having the given degree and zeros.

Degree 4 ; zeros: -5-2i ; 1 multiplicity 2

f(x)= a( )

Answer 1

If this is a root, then its conjugate is a root also.

-5-2i , conjugate -5 + 2i

Answer 2

1 multiplicity 2

means that 1 is a double root.

Answer 3

-5-2i , -5 + 2i , 1, and 1 are the 4 roots
