How do I expand: (x-i)(x+i)(x-4+i)(x-4-i)(x-2+i)(x-2-i)? Thanks in advance!

do you see (a-b)(a+b) pattern?

You mean the (x-4-i)(x-4+i), etc.?
BAdhi
  • BAdhi
yeah.. and notice the property \((a+b)(a-b) = (a^2-b^2)\)

(x-i)(x+i) = (x^2-i^2) = x^ + 1?

Yeah 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
