3w^2-12w=-12

解

3 w^{2} - 12 w = - 12

w = 2

解答ステップ

3 w^{2} - 12 w = - 12

3 w^{2} - 12 w + 12 = 0

解くとthe二次式

w_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 3 \cdot 12}{2 \cdot 3}

(- 12)^{2} - 4 \cdot 3 \cdot 12 = 0

w_{1, 2} = \frac{- ( - 12 ) \pm 0}{2 \cdot 3}

w = \frac{- ( - 12 )}{2 \cdot 3}

\frac{- ( - 12 )}{2 \cdot 3} = 2

w = 2

二次equationの解:

w = 2
