how do u solve for this? sqrt(-10i+12)

Hello, good afternoon. I need help with my precalc hw. we are learning about finding zeros I don't which method I should use for this problem: if i is a zero of x^3+3x^2+ix+(4+i) what do i do? synthetic divison? or long division? when i did long division...

how do i do this? factor x^4-x^2-20 over real and complex numbers I tried to do synthetic, but it doesnt work.=(

WOAH. how did u know how to do that? like, waht is the rule? is gedunken a person?

what do u mean looking atthe end "you know one root has to be i" what does that mean?

you get x^2+(3+i)x+(4i-1) what do i do next?
