18x^2-12x+2=0

解

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

x = \frac{1}{3}

十進法表記

x = 0.33333 \dots

解答ステップ

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

解くとthe二次式

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 18 \cdot 2}{2 \cdot 18}

(- 12)^{2} - 4 \cdot 18 \cdot 2 = 0

x_{1, 2} = \frac{- ( - 12 ) \pm 0}{2 \cdot 18}

x = \frac{- ( - 12 )}{2 \cdot 18}

\frac{- ( - 12 )}{2 \cdot 18} = \frac{1}{3}

x = \frac{1}{3}

二次equationの解:

x = \frac{1}{3}
