Algebra 2 Math Question

I really need help on this one part. If someone could help me it would be a BIG help! smile

Given the 3 x-intercepts (i,-i, and 2)
Write a polynomial equation

I really just need help on how to unfactor the -i back into polynomial form. Thanks.

Ok John I'll try your solution to it. Maybe I'm overthinking this and it's simpler than I imagine.
