Which polynomial function has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1?
f(x) = (x – 2i)(x – 3i)
f(x) = (x + 2i)(x + 3i)
f(x) = (x – 2)(x – 3)(x – 2i)(x – 3i)
f(x) = (x + 2i)(x + 3i)(x – 2i)(x – 3i)

yea i do i found that i have to accually read the problem too lol

Well you need to find the roots of each function, and that is done by setting f(x) to be 0 and solve for x, so for the first one it would be
f(x) = (x – 2i)(x – 3i) which can be broken up into:
0 = (x – 2i) => x = 2i
0 = (x – 3i) => x = 3i
and a multiplicity of one makes A the only answer.

oh DUA i completly forgot lol
