x^2+(1/3)^2=1

解

x^{2} + (\frac{1}{3})^{2} = 1

解

x = \frac{2 2}{3}, x = - \frac{2 2}{3}

+1

十進法表記

x = 0.94280 \dots, x = - 0.94280 \dots

解答ステップ

x^{2} + (\frac{1}{3})^{2} = 1

拡張

x^{2} + (\frac{1}{3})^{2} : x^{2} + \frac{1}{9}

x^{2} + \frac{1}{9} = 1

\frac{1}{9}

を右側に移動します

x^{2} = 1 - \frac{1}{9}

簡素化

1 - \frac{1}{9} : \frac{8}{9}

x^{2} = f (a)

の場合, 解は

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

x = \frac{8}{9}, x = - \frac{8}{9}

\frac{8}{9} = \frac{2 2}{3}

- \frac{8}{9} = - \frac{2 2}{3}

x = \frac{2 2}{3}, x = - \frac{2 2}{3}

(-3x^2-16x)/(12)+7=0

\frac{- 3 x ^{2} - 16 x}{12} + 7 = 0

3 x^{2} + 16 x = 0
