x^2+23x+132=0

解

x^{2} + 23 x + 132 = 0

x = - 11, x = - 12

解答ステップ

x^{2} + 23 x + 132 = 0

解くとthe二次式

x_{1, 2} = \frac{- 23 \pm 2 3 ^{2} - 4 \cdot 1 \cdot 132}{2 \cdot 1}

2 3^{2} - 4 \cdot 1 \cdot 132 = 1

x_{1, 2} = \frac{- 23 \pm 1}{2 \cdot 1}

解を分離する

x_{1} = \frac{- 23 + 1}{2 \cdot 1}, x_{2} = \frac{- 23 - 1}{2 \cdot 1}

x = \frac{- 23 + 1}{2 \cdot 1} : - 11

x = \frac{- 23 - 1}{2 \cdot 1} : - 12

二次equationの解:

x = - 11, x = - 12
