Ok so I did what you said and then did the quadratic formula so i have 4 roots but how do I form quadratic formulas?

the book asks to fnd the four roots of z to the fourth power + 4 = 0 and then use to demonstrate that z to the fourth power + 4 can be factored into two quadratics with real coefficinets. I am clueless on where to start. Please help.

That is what the book says except the book uses radians instead of degrees

I am confused on a homework problem. It states that the Arg(z1z2) = Arg (z1) + Arg (z2) if -90 < z1 >/= 90 , and -90 < z2 >/= 90 , describe the set of points that meet this criteria? I am not sure how to answer this, I'm not sure I know entirely what they are asking. I haven't taken a math...
