4m^2+9=-16

解

4 m^{2} + 9 = - 16

m = \frac{5}{2} i, m = - \frac{5}{2} i

解答ステップ

4 m^{2} + 9 = - 16

9

を右側に移動します

4 m^{2} = - 25

以下で両辺を割る

4

m^{2} = - \frac{25}{4}

x^{2} = f (a)

の場合, 解は

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

m = - \frac{25}{4}, m = - - \frac{25}{4}

- \frac{25}{4} = \frac{5}{2} i

- - \frac{25}{4} = - \frac{5}{2} i

m = \frac{5}{2} i, m = - \frac{5}{2} i
