Answer 2

1.$5x ^ { 2 } -2x+1 \\ = x ^ 2 -\frac{2}{5}x +\frac{1}{5} = 0 \\ = \: r + s = \frac{2}{5} \\ rs = \frac{1}{5} \\ \\ = r = \frac{1}{5} - u \\ = s = \frac{1}{5} + u \\ = (\frac{1}{5} - u) (\frac{1}{5} + u) = \frac{1}{5} \\ = \frac{1}{25} - u^2 = \frac{1}{5} \\ = -u^2 = \frac{1}{5}-\frac{1}{25} = \frac{4}{25} \\ = u^2 = -\frac{4}{25} \\ u = \pm\sqrt{-\frac{4}{25}} = \pm \frac{2}{5}i \\ = r =\frac{1}{5} - \frac{2}{5}i = 0.200 - 0.400i \\ s = \frac{1}{5} + \frac{2}{5}i = 0.200 + 0.400i$
