Suppose a + ib is a root of p() (so p(a + ib) = 0). Show
Chapter , Problem 9(choose chapter or problem)
Suppose a + ib is a root of p() (so p(a + ib) = 0). Show that a ib is also a root. [Hint: Remember that a complex number is zero if and only if both its real and imaginary parts are zero. Then compute p(a + ib) and p(a ib).]
