Question

XWhich polynomial function has a leading coefficient of 1 and roots (7 + i) and (5 – i) with multiplicity 1?

Answer 1

Hello,

If ALL coefficients of x are reals!, (question is wrong)
if $z_{0}\ is\ a\ root\ \overline{z_{0}}\ is\ also\ a\ root$

Thus ANSWER C f(x) = (x – (7 – i)) (x – (5 + i)) (x – (7 + i)) (x – (5 – i))
