71096.06=(60+2m)*(40+2m)

解

71096.06 = (60 + 2 m) \cdot (40 + 2 m)

解

m = \frac{- 20000 + 11391369600}{800}, m = \frac{- 20000 - 11391369600}{800}

+1

十進法表記

m = 108.41294 \dots, m = - 158.41294 \dots

解答ステップ

71096.06 = (60 + 2 m) (40 + 2 m)

以下で両辺を乗じる:

100

7109606 = (60 + 2 m) (40 + 2 m) \cdot 100

拡張

(60 + 2 m) (40 + 2 m) \cdot 100 : 240000 + 20000 m + 400 m^{2}

7109606 = 240000 + 20000 m + 400 m^{2}

辺を交換する

240000 + 20000 m + 400 m^{2} = 7109606

7109606

400 m^{2} + 20000 m - 6869606 = 0

解くとthe二次式

m_{1, 2} = \frac{- 20000 \pm 2000 0 ^{2} - 4 \cdot 400 ( - 6869606 )}{2 \cdot 400}

2000 0^{2} - 4 \cdot 400 (- 6869606) = 11391369600

m_{1, 2} = \frac{- 20000 \pm 11391369600}{2 \cdot 400}

解を分離する

m_{1} = \frac{- 20000 + 11391369600}{2 \cdot 400}, m_{2} = \frac{- 20000 - 11391369600}{2 \cdot 400}

m = \frac{- 20000 + 11391369600}{2 \cdot 400} : \frac{- 20000 + 11391369600}{800}

m = \frac{- 20000 - 11391369600}{2 \cdot 400} : \frac{- 20000 - 11391369600}{800}

二次equationの解:

m = \frac{- 20000 + 11391369600}{800}, m = \frac{- 20000 - 11391369600}{800}
