0.010893x^2-0.07492x+0.1012=0

解

0.010893 x^{2} - 0.07492 x + 0.1012 = 0

x = \frac{0.07492 + 0.00120352}{0.021786}, x = \frac{0.07492 - 0.00120352}{0.021786}

十進法表記

x = 5.03129 \dots, x = 1.84651 \dots

解答ステップ

0.010893 x^{2} - 0.07492 x + 0.1012 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 0.07492 ) \pm ( - 0.07492 ) ^{2} - 4 \cdot 0.010893 \cdot 0.1012}{2 \cdot 0.010893}

(- 0.07492)^{2} - 4 \cdot 0.010893 \cdot 0.1012 = 0.00120352

x_{1, 2} = \frac{- ( - 0.07492 ) \pm 0.00120352}{2 \cdot 0.010893}

解を分離する

x_{1} = \frac{- ( - 0.07492 ) + 0.00120352}{2 \cdot 0.010893}, x_{2} = \frac{- ( - 0.07492 ) - 0.00120352}{2 \cdot 0.010893}

x = \frac{- ( - 0.07492 ) + 0.00120352}{2 \cdot 0.010893} : \frac{0.07492 + 0.00120352}{0.021786}

x = \frac{- ( - 0.07492 ) - 0.00120352}{2 \cdot 0.010893} : \frac{0.07492 - 0.00120352}{0.021786}

二次equationの解:

x = \frac{0.07492 + 0.00120352}{0.021786}, x = \frac{0.07492 - 0.00120352}{0.021786}
