Question

How can I find the zero while factoring for the equation I circled?

Answer 1

Below

Explanation:

x^2 -x + 1 Use Quadratic Formula a = 1 b = -1 c = 1

to find zeroes 1/2 ± i sqrt(3) / 3

Sooo.... Not sure you could find it by factoring:

(x -1/2 +i sqrt(3) /2) (x - 1/2 - i sqrt (3)/2) would be hard to see !!
