x^2+5x+24=0

解

x^{2} + 5 x + 24 = 0

解

x = - \frac{5}{2} + i \frac{71}{2}, x = - \frac{5}{2} - i \frac{71}{2}

解答ステップ

x^{2} + 5 x + 24 = 0

解くとthe二次式

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 1 \cdot 24}{2 \cdot 1}

簡素化

5^{2} - 4 \cdot 1 \cdot 24 : 71 i

x_{1, 2} = \frac{- 5 \pm 71 i}{2 \cdot 1}

解を分離する

x_{1} = \frac{- 5 + 71 i}{2 \cdot 1}, x_{2} = \frac{- 5 - 71 i}{2 \cdot 1}

x = \frac{- 5 + 71 i}{2 \cdot 1} : - \frac{5}{2} + i \frac{71}{2}

x = \frac{- 5 - 71 i}{2 \cdot 1} : - \frac{5}{2} - i \frac{71}{2}

二次equationの解:

x = - \frac{5}{2} + i \frac{71}{2}, x = - \frac{5}{2} - i \frac{71}{2}
