64x^2+9=0

解

64 x^{2} + 9 = 0

x = \frac{3}{8} i, x = - \frac{3}{8} i

解答ステップ

64 x^{2} + 9 = 0

9

を右側に移動します

64 x^{2} = - 9

以下で両辺を割る

64

x^{2} = - \frac{9}{64}

x^{2} = f (a)

の場合, 解は

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

x = - \frac{9}{64}, x = - - \frac{9}{64}

- \frac{9}{64} = \frac{3}{8} i

- - \frac{9}{64} = - \frac{3}{8} i

x = \frac{3}{8} i, x = - \frac{3}{8} i
