36x^2-48x+16=0

解

36 x^{2} - 48 x + 16 = 0

x = \frac{2}{3}

十進法表記

x = 0.66666 \dots

解答ステップ

36 x^{2} - 48 x + 16 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 48 ) \pm ( - 48 ) ^{2} - 4 \cdot 36 \cdot 16}{2 \cdot 36}

(- 48)^{2} - 4 \cdot 36 \cdot 16 = 0

x_{1, 2} = \frac{- ( - 48 ) \pm 0}{2 \cdot 36}

x = \frac{- ( - 48 )}{2 \cdot 36}

\frac{- ( - 48 )}{2 \cdot 36} = \frac{2}{3}

x = \frac{2}{3}

二次equationの解:

x = \frac{2}{3}
