Question

x7+1=0
find all complete roots​

Answer 1

Answer:

Step-by-step explanation:I'm struggling to figure out how to find the roots of this question.

If w is a complex root of the equation:

x7−1=0

show that w2,w3,w4,w5,w6

are the other complex roots.

I know that you can factorise it into:

(x−1)(x6+x5+x4+x3+x2+x+1)=0

But I don't know where to go from there.

Any help is greatly appreciated!
