0=x^2-12x+36

解

0 = x^{2} - 12 x + 36

x = 6

解答ステップ

0 = x^{2} - 12 x + 36

辺を交換する

x^{2} - 12 x + 36 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 1 \cdot 36}{2 \cdot 1}

(- 12)^{2} - 4 \cdot 1 \cdot 36 = 0

x_{1, 2} = \frac{- ( - 12 ) \pm 0}{2 \cdot 1}

x = \frac{- ( - 12 )}{2 \cdot 1}

\frac{- ( - 12 )}{2 \cdot 1} = 6

x = 6

二次equationの解:

x = 6
