x+(12)/x =-3

解

x + \frac{12}{x} = - 3

x = - \frac{3}{2} + i \frac{39}{2}, x = - \frac{3}{2} - i \frac{39}{2}

解答ステップ

x + \frac{12}{x} = - 3

以下で両辺を乗じる:

x

x^{2} + 12 = - 3 x

解く

x^{2} + 12 = - 3 x : x = - \frac{3}{2} + i \frac{39}{2}, x = - \frac{3}{2} - i \frac{39}{2}

x = - \frac{3}{2} + i \frac{39}{2}, x = - \frac{3}{2} - i \frac{39}{2}
