Thanks in advance!

Best ResponseYou've already chosen the best response.0You mean the (x4i)(x4+i), etc.?

Best ResponseYou've already chosen the best response.3yeah.. and notice the property \((a+b)(ab) = (a^2b^2)\)

Best ResponseYou've already chosen the best response.0Yeah it was @zzr0ck3r, I was able to figure it out in the end, the question asked to form a polynomial function out of the given degree and zero values using real coefficients so I just really needed help expanding it more than anything. I managed to solve it though I believe if you check my work ^ Anyway, thanks @BAdhi and @zzr0ck3r
