2X^2-12X=0

解

2 X^{2} - 12 X = 0

X = 6, X = 0

解答ステップ

2 X^{2} - 12 X = 0

解くとthe二次式

X_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 2 \cdot 0}{2 \cdot 2}

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

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

解を分離する

X_{1} = \frac{- ( - 12 ) + 12}{2 \cdot 2}, X_{2} = \frac{- ( - 12 ) - 12}{2 \cdot 2}

X = \frac{- ( - 12 ) + 12}{2 \cdot 2} : 6

X = \frac{- ( - 12 ) - 12}{2 \cdot 2} : 0

二次equationの解:

X = 6, X = 0
