2.32=-0.0007h^2+0.015h+3.02

解

2.32 = - 0.0007 h^{2} + 0.015 h + 3.02

解

h = - \frac{- 0.015 + 0.002185}{0.0014}, h = \frac{0.015 + 0.002185}{0.0014}

+1

十進法表記

h = - 22.67427 \dots, h = 44.10284 \dots

解答ステップ

2.32 = - 0.0007 h^{2} + 0.015 h + 3.02

辺を交換する

- 0.0007 h^{2} + 0.015 h + 3.02 = 2.32

- 0.0007 h^{2} + 0.015 h + 0.7 = 0

解くとthe二次式

h_{1, 2} = \frac{- 0.015 \pm 0.01 5 ^{2} - 4 ( - 0.0007 ) \cdot 0.7}{2 ( - 0.0007 )}

0.01 5^{2} - 4 (- 0.0007) \cdot 0.7 = 0.002185

h_{1, 2} = \frac{- 0.015 \pm 0.002185}{2 ( - 0.0007 )}

解を分離する

h_{1} = \frac{- 0.015 + 0.002185}{2 ( - 0.0007 )}, h_{2} = \frac{- 0.015 - 0.002185}{2 ( - 0.0007 )}

h = \frac{- 0.015 + 0.002185}{2 ( - 0.0007 )} : - \frac{- 0.015 + 0.002185}{0.0014}

h = \frac{- 0.015 - 0.002185}{2 ( - 0.0007 )} : \frac{0.015 + 0.002185}{0.0014}

二次equationの解:

h = - \frac{- 0.015 + 0.002185}{0.0014}, h = \frac{0.015 + 0.002185}{0.0014}
