2(x^2+7)=x^2+10

解

2 (x^{2} + 7) = x^{2} + 10

解

x = 2 i, x = - 2 i

解答ステップ

2 (x^{2} + 7) = x^{2} + 10

拡張

2 (x^{2} + 7) : 2 x^{2} + 14

2 x^{2} + 14 = x^{2} + 10

14

を右側に移動します

2 x^{2} = x^{2} - 4

x^{2}

を左側に移動します

x^{2} = - 4

x^{2} = f (a)

の場合, 解は

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

x = - 4, x = - - 4

- 4 = 2 i

- - 4 = - 2 i

x = 2 i, x = - 2 i
