x1=1x_{1} = 1
=
11
=
1

y1=2y_{1} = 2
=
22
=
2
x2=(−32−7i2)(−12−7i2)2x_{2} = \frac{\left(- \frac{3}{2} - \frac{\sqrt{7} i}{2}\right) \left(- \frac{1}{2} - \frac{\sqrt{7} i}{2}\right)}{2}
=
−12+7i2- \frac{1}{2} + \frac{\sqrt{7} i}{2}
=
-0.5 + 1.3228756555323*i

y2=−12−7i2y_{2} = - \frac{1}{2} - \frac{\sqrt{7} i}{2}
=
−12−7i2- \frac{1}{2} - \frac{\sqrt{7} i}{2}
=
-0.5 - 1.3228756555323*i
x3=(−32+7i2)(−12+7i2)2x_{3} = \frac{\left(- \frac{3}{2} + \frac{\sqrt{7} i}{2}\right) \left(- \frac{1}{2} + \frac{\sqrt{7} i}{2}\right)}{2}
=
−12−7i2- \frac{1}{2} - \frac{\sqrt{7} i}{2}
=
-0.5 - 1.3228756555323*i

y3=−12+7i2y_{3} = - \frac{1}{2} + \frac{\sqrt{7} i}{2}
=
−12+7i2- \frac{1}{2} + \frac{\sqrt{7} i}{2}
=
-0.5 + 1.3228756555323*i
