(a) a@^2+b@+c=0, where a,b,c are real, @ is complex. Show that a(@conj)^2+b(@conj)+c=0
(b) Deduce that if @ is a non-real root of ax^2+bx+c=0, where a,b,c are real, then (@ conj) is the other root of this quadratic equation
i dunno, it looks easy, but i think i'm missing something :S
(sorry^ either latex wasn't adding spaces or i just dont know how to use it
)
