1+3x^2=0

解

1 + 3 x^{2} = 0

x = \frac{1}{3} i, x = - \frac{1}{3} i

解答ステップ

1 + 3 x^{2} = 0

1

を右側に移動します

3 x^{2} = - 1

以下で両辺を割る

3

x^{2} = - \frac{1}{3}

x^{2} = f (a)

の場合, 解は

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

x = - \frac{1}{3}, x = - - \frac{1}{3}

- \frac{1}{3} = \frac{1}{3} i

- - \frac{1}{3} = - \frac{1}{3} i

x = \frac{1}{3} i, x = - \frac{1}{3} i
