(x^2)/4 = 2/(x^2+1)

解

\frac{x ^{2}}{4} = \frac{2}{x ^{2} + 1}

x = \frac{- 1 + 33}{2}, x = - \frac{- 1 + 33}{2}, x = \frac{- 1 - 33}{2}, x = - \frac{- 1 - 33}{2}

解答ステップ

\frac{x ^{2}}{4} = \frac{2}{x ^{2} + 1}

x^{2} (x^{2} + 1) = 8

解く

x^{2} (x^{2} + 1) = 8 : x = \frac{- 1 + 33}{2}, x = - \frac{- 1 + 33}{2}, x = \frac{- 1 - 33}{2}, x = - \frac{- 1 - 33}{2}

x = \frac{- 1 + 33}{2}, x = - \frac{- 1 + 33}{2}, x = \frac{- 1 - 33}{2}, x = - \frac{- 1 - 33}{2}
