9r^2-3=-152

解

9 r^{2} - 3 = - 152

r = \frac{149}{3} i, r = - \frac{149}{3} i

解答ステップ

9 r^{2} - 3 = - 152

3

を右側に移動します

9 r^{2} = - 149

以下で両辺を割る

9

r^{2} = - \frac{149}{9}

x^{2} = f (a)

の場合, 解は

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

r = - \frac{149}{9}, r = - - \frac{149}{9}

- \frac{149}{9} = \frac{149}{3} i

- - \frac{149}{9} = - \frac{149}{3} i

r = \frac{149}{3} i, r = - \frac{149}{3} i
