Hey if anyone could help me to understand wat to do in this question I would be appreciative!(adsbygoogle = window.adsbygoogle || []).push({});

Find in the complex plane the fourth roots of -64, Use the result to factor

Z^4+ 64 into

i) a product of four linear factors

I kinda thought that you could write something along the lines of this froman example id seen!

(z+64)(z+b)(z+c)(z+d), but I wouldnt know how to find the rest!

If I can be helped to work out this answer then I could work out the next most likely!

ii) a product of two quadratic factors with real coefficients!
