Based on the Fundamental Theorem of Algebra, how many complex roots does each of the following equations have? Write your answer as a number in the space provided. For example, if there are twelve complex roots, type 12.

x(x2 - 4)(x2 + 16) = 0 has
a0 complex roots

(x 2 + 4)(x + 5)2 = 0 has
a1 complex roots

x6 - 4x5 - 24x2 + 10x - 3 = 0 has
a2 complex roots

x7 + 128 = 0 has
a3 complex roots

(x3 + 9)(x2 - 4) = 0 has
a4 complex roots
