    complex no. question

    yeah thats what stuffed me up. i kept tryin to make the question 2 hard by doin quadratic formula and squaring the discriminant and all those methods, whan all i realy needed 2 do was simple.

    complex no. question

    This question is from the cambridge book but i cant seem to get the same answer as them, and bacause the solutions arnt worked at all........ i though i someone might be able to shed some light on it. solve. x^2 + (2 - i)x - 2i = 0 (its question 4(b) in the diagnostic test 2)
