1/2 x^2+8x+32=0

解

\frac{1}{2} x^{2} + 8 x + 32 = 0

x = - 8

解答ステップ

\frac{1}{2} x^{2} + 8 x + 32 = 0

以下で両辺を乗じる:

2

x^{2} + 16 x + 64 = 0

解くとthe二次式

x_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 \cdot 1 \cdot 64}{2 \cdot 1}

1 6^{2} - 4 \cdot 1 \cdot 64 = 0

x_{1, 2} = \frac{- 16 \pm 0}{2 \cdot 1}

x = \frac{- 16}{2 \cdot 1}

\frac{- 16}{2 \cdot 1} = - 8

x = - 8

二次equationの解:

x = - 8
