x^2+0.000064x-0.00000024=0

解

x^{2} + 0.000064 x - 0.00000024 = 0

x = \frac{- 0.000064 + 9.64096 E - 7}{2}, x = \frac{- 0.000064 - 9.64096 E - 7}{2}

十進法表記

x = 0.00045 \dots, x = - 0.00052 \dots

解答ステップ

x^{2} + 0.000064 x - 0.00000024 = 0

解くとthe二次式

x_{1, 2} = \frac{- 0.000064 \pm 0.00006 4 ^{2} - 4 \cdot 1 \cdot ( - 0.00000024 )}{2 \cdot 1}

0.00006 4^{2} - 4 \cdot 1 \cdot (- 0.00000024) = 9.64096 E - 7

x_{1, 2} = \frac{- 0.000064 \pm 9.64096 E - 7}{2 \cdot 1}

解を分離する

x_{1} = \frac{- 0.000064 + 9.64096 E - 7}{2 \cdot 1}, x_{2} = \frac{- 0.000064 - 9.64096 E - 7}{2 \cdot 1}

x = \frac{- 0.000064 + 9.64096 E - 7}{2 \cdot 1} : \frac{- 0.000064 + 9.64096 E - 7}{2}

x = \frac{- 0.000064 - 9.64096 E - 7}{2 \cdot 1} : \frac{- 0.000064 - 9.64096 E - 7}{2}

二次equationの解:

x = \frac{- 0.000064 + 9.64096 E - 7}{2}, x = \frac{- 0.000064 - 9.64096 E - 7}{2}
