(11x-1)^2-2(11x-1)-3=0

解

(11 x - 1)^{2} - 2 (11 x - 1) - 3 = 0

解

x = \frac{4}{11}, x = 0

+1

十進法表記

x = 0.36363 \dots, x = 0

解答ステップ

(11 x - 1)^{2} - 2 (11 x - 1) - 3 = 0

拡張

(11 x - 1)^{2} - 2 (11 x - 1) - 3 : 121 x^{2} - 44 x

121 x^{2} - 44 x = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 44 ) \pm ( - 44 ) ^{2} - 4 \cdot 121 \cdot 0}{2 \cdot 121}

(- 44)^{2} - 4 \cdot 121 \cdot 0 = 44

x_{1, 2} = \frac{- ( - 44 ) \pm 44}{2 \cdot 121}

解を分離する

x_{1} = \frac{- ( - 44 ) + 44}{2 \cdot 121}, x_{2} = \frac{- ( - 44 ) - 44}{2 \cdot 121}

x = \frac{- ( - 44 ) + 44}{2 \cdot 121} : \frac{4}{11}

x = \frac{- ( - 44 ) - 44}{2 \cdot 121} : 0

二次equationの解:

x = \frac{4}{11}, x = 0
