x^2-14x-32=0

解

x^{2} - 14 x - 32 = 0

x = 16, x = - 2

解答ステップ

x^{2} - 14 x - 32 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 14 ) \pm ( - 14 ) ^{2} - 4 \cdot 1 \cdot ( - 32 )}{2 \cdot 1}

(- 14)^{2} - 4 \cdot 1 \cdot (- 32) = 18

x_{1, 2} = \frac{- ( - 14 ) \pm 18}{2 \cdot 1}

解を分離する

x_{1} = \frac{- ( - 14 ) + 18}{2 \cdot 1}, x_{2} = \frac{- ( - 14 ) - 18}{2 \cdot 1}

x = \frac{- ( - 14 ) + 18}{2 \cdot 1} : 16

x = \frac{- ( - 14 ) - 18}{2 \cdot 1} : - 2

二次equationの解:

x = 16, x = - 2
