7(4x-3)^2-15=-68

解

7 (4 x - 3)^{2} - 15 = - 68

解

x = \frac{3}{4} + i \frac{371}{28}, x = \frac{3}{4} - i \frac{371}{28}

解答ステップ

7 (4 x - 3)^{2} - 15 = - 68

15

を右側に移動します

7 (4 x - 3)^{2} = - 53

以下で両辺を割る

7

(4 x - 3)^{2} = - \frac{53}{7}

(g (x))^{2} = f (a)

の場合, 解は

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

解く

4 x - 3 = - \frac{53}{7} : x = \frac{3}{4} + i \frac{371}{28}

解く

4 x - 3 = - - \frac{53}{7} : x = \frac{3}{4} - i \frac{371}{28}

二次equationの解:

x = \frac{3}{4} + i \frac{371}{28}, x = \frac{3}{4} - i \frac{371}{28}
