-70p^2+240p+366=0

解

- 70 p^{2} + 240 p + 366 = 0

p = - \frac{- 60 + 10005}{35}, p = \frac{60 + 10005}{35}

十進法表記

p = - 1.14357 \dots, p = 4.57214 \dots

解答ステップ

- 70 p^{2} + 240 p + 366 = 0

解くとthe二次式

p_{1, 2} = \frac{- 240 \pm 24 0 ^{2} - 4 ( - 70 ) \cdot 366}{2 ( - 70 )}

24 0^{2} - 4 (- 70) \cdot 366 = 410005

p_{1, 2} = \frac{- 240 \pm 4 10005}{2 ( - 70 )}

解を分離する

p_{1} = \frac{- 240 + 4 10005}{2 ( - 70 )}, p_{2} = \frac{- 240 - 4 10005}{2 ( - 70 )}

p = \frac{- 240 + 4 10005}{2 ( - 70 )} : - \frac{- 60 + 10005}{35}

p = \frac{- 240 - 4 10005}{2 ( - 70 )} : \frac{60 + 10005}{35}

二次equationの解:

p = - \frac{- 60 + 10005}{35}, p = \frac{60 + 10005}{35}
