um x-3+i

Answer 4

x-3+i

Answer 5

good just be careful with parentheses

x-(3+i) and x - (3-i)

Answer 6

for part II) the two complex roots are x-(3+i) and x - (3-i) so multiply these together to get the quadratic (just be careful with parentheses/signs)

Answer 7

-2x-1xi-3+i

Answer 8

your final answer should not have i in it, check your calculations again

(x-(3+i)) * (x-(3-i))

^ use foil

Answer 9

x^2-6x+10

Answer 10

good

for part III the last factor is (x-3) so multiply that polynomial to get the answer for III

Answer 11

x^2+6x-3

Answer 12

(x-3)(x^2-6x+10) = ?

Answer 13

x^3-9x^2+28x-30
