Question
Find the three roots of the equation x^3=1

Answer
x^3 = 1
x^3 - 1 = 0
(x - 1)(x^2 + x + 1)

x^2 + x + 1
x = (-b ± sqrt(b^2 - 4ac))/2a

x = (-1 ± sqrt(1^2 - 4(1)(1)))/(2(1))
x = (-1 ± sqrt(1 - 4))/2
x = (-1 ± sqrt(-3))/2
x = (-1 ± isqrt(3))/2

x = 1, (1/2)(-1 + isqrt(3)), and (1/2)(-1 - sqrt(3))
