x^2+(-(sqrt(2))/2)^2=1

解

x^{2} + (- \frac{2}{2})^{2} = 1

解

x = \frac{1}{2}, x = - \frac{1}{2}

+1

十進法表記

x = 0.70710 \dots, x = - 0.70710 \dots

解答ステップ

x^{2} + (- \frac{2}{2})^{2} = 1

拡張

x^{2} + (- \frac{2}{2})^{2} : x^{2} + \frac{1}{2}

x^{2} + \frac{1}{2} = 1

\frac{1}{2}

を右側に移動します

x^{2} = 1 - \frac{1}{2}

簡素化

1 - \frac{1}{2} : \frac{1}{2}

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

x = \frac{1}{2}, x = - \frac{1}{2}

\frac{1}{2} = \frac{1}{2}

- \frac{1}{2} = - \frac{1}{2}

x = \frac{1}{2}, x = - \frac{1}{2}
