A polynomial of degree 4, P(x) has leading coefficient 1, and has roots of -3 + i and 3 with multiplicity 2.

Question

Find the possible formula for P(x). You do not need to simplify your answer.

P(x) =

Answer format should look like (x-a)^2(x-(b+i))(x-(b-i))

Answer 1

P(x) = (x - 3)²(x - (-3 + i))(x - (-3 -i))
