9m^2+54=5

解

9 m^{2} + 54 = 5

m = \frac{7}{3} i, m = - \frac{7}{3} i

解答ステップ

9 m^{2} + 54 = 5

54

を右側に移動します

9 m^{2} = - 49

以下で両辺を割る

9

m^{2} = - \frac{49}{9}

x^{2} = f (a)

の場合, 解は

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

m = - \frac{49}{9}, m = - - \frac{49}{9}

- \frac{49}{9} = \frac{7}{3} i

- - \frac{49}{9} = - \frac{7}{3} i

m = \frac{7}{3} i, m = - \frac{7}{3} i
