(0.00000064-x)(0.00000114-x)=4.1E-13

解

(0.00000064 - x) (0.00000114 - x) = 4.1 E - 13

解

x = \frac{0.00000178 + 1.89 E - 12}{2}, x = \frac{0.00000178 - 1.89 E - 12}{2}

+1

十進法表記

x = 1.57739 E - 6, x = 2.02614 E - 7

解答ステップ

(0.00000064 - x) (0.00000114 - x) = 4.1 E - 13

拡張

(0.00000064 - x) (0.00000114 - x) : 7.296 E - 13 - 0.00000178 x + x^{2}

7.296 E - 13 - 0.00000178 x + x^{2} = 4.1 E - 13

4.1 E - 13

を左側に移動します

x^{2} - 0.00000178 x + 3.196 E - 13 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 0.00000178 ) \pm ( - 0.00000178 ) ^{2} - 4 \cdot 1 \cdot 3.196 E - 13}{2 \cdot 1}

(- 0.00000178)^{2} - 4 \cdot 1 \cdot 3.196 E - 13 = 1.89 E - 12

x_{1, 2} = \frac{- ( - 0.00000178 ) \pm 1.89 E - 12}{2 \cdot 1}

解を分離する

x_{1} = \frac{- ( - 0.00000178 ) + 1.89 E - 12}{2 \cdot 1}, x_{2} = \frac{- ( - 0.00000178 ) - 1.89 E - 12}{2 \cdot 1}

x = \frac{- ( - 0.00000178 ) + 1.89 E - 12}{2 \cdot 1} : \frac{0.00000178 + 1.89 E - 12}{2}

x = \frac{- ( - 0.00000178 ) - 1.89 E - 12}{2 \cdot 1} : \frac{0.00000178 - 1.89 E - 12}{2}

二次equationの解:

x = \frac{0.00000178 + 1.89 E - 12}{2}, x = \frac{0.00000178 - 1.89 E - 12}{2}
