5x^2-36=0

解

5 x^{2} - 36 = 0

解

x = \frac{6}{5}, x = - \frac{6}{5}

+1

十進法表記

x = 2.68328 \dots, x = - 2.68328 \dots

解答ステップ

5 x^{2} - 36 = 0

36

を右側に移動します

5 x^{2} = 36

以下で両辺を割る

5

x^{2} = \frac{36}{5}

x^{2} = f (a)

の場合, 解は

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

x = \frac{36}{5}, x = - \frac{36}{5}

\frac{36}{5} = \frac{6}{5}

- \frac{36}{5} = - \frac{6}{5}

x = \frac{6}{5}, x = - \frac{6}{5}
