9x^2-24x+16=0

解

9 x^{2} - 24 x + 16 = 0

x = \frac{4}{3}

十進法表記

x = 1.33333 \dots

解答ステップ

9 x^{2} - 24 x + 16 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 24 ) \pm ( - 24 ) ^{2} - 4 \cdot 9 \cdot 16}{2 \cdot 9}

(- 24)^{2} - 4 \cdot 9 \cdot 16 = 0

x_{1, 2} = \frac{- ( - 24 ) \pm 0}{2 \cdot 9}

x = \frac{- ( - 24 )}{2 \cdot 9}

\frac{- ( - 24 )}{2 \cdot 9} = \frac{4}{3}

x = \frac{4}{3}

二次equationの解:

x = \frac{4}{3}
