1+4x^2=0

解

1 + 4 x^{2} = 0

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

解答ステップ

1 + 4 x^{2} = 0

1

を右側に移動します

4 x^{2} = - 1

以下で両辺を割る

4

x^{2} = - \frac{1}{4}

x^{2} = f (a)

の場合, 解は

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

x = - \frac{1}{4}, x = - - \frac{1}{4}

- \frac{1}{4} = \frac{1}{2} i

- - \frac{1}{4} = - \frac{1}{2} i

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