3n^2+10n=-12-8n^2+10n

解

3 n^{2} + 10 n = - 12 - 8 n^{2} + 10 n

n = \frac{2 3}{11} i, n = - \frac{2 3}{11} i

解答ステップ

3 n^{2} + 10 n = - 12 - 8 n^{2} + 10 n

10 n

を左側に移動します

3 n^{2} = - 12 - 8 n^{2}

8 n^{2}

を左側に移動します

11 n^{2} = - 12

以下で両辺を割る

11

n^{2} = - \frac{12}{11}

x^{2} = f (a)

の場合, 解は

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

n = - \frac{12}{11}, n = - - \frac{12}{11}

- \frac{12}{11} = \frac{2 3}{11} i

- - \frac{12}{11} = - \frac{2 3}{11} i

n = \frac{2 3}{11} i, n = - \frac{2 3}{11} i
