85.183x^2-174.9x+93.362=34

解

85.183 x^{2} - 174.9 x + 93.362 = 34

解

x = \frac{174900 + 17490 0 ^{2} - 20226532984}{170366}, x = \frac{174900 - 17490 0 ^{2} - 20226532984}{170366}

+1

十進法表記

x = 1.62415 \dots, x = 0.42906 \dots

解答ステップ

85.183 x^{2} - 174.9 x + 93.362 = 34

以下で両辺を乗じる:

1000

85183 x^{2} - 174900 x + 93362 = 34000

85183 x^{2} - 174900 x + 59362 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 174900 ) \pm ( - 174900 ) ^{2} - 4 \cdot 85183 \cdot 59362}{2 \cdot 85183}

(- 174900)^{2} - 4 \cdot 85183 \cdot 59362 = 17490 0^{2} - 20226532984

x_{1, 2} = \frac{- ( - 174900 ) \pm 17490 0 ^{2} - 20226532984}{2 \cdot 85183}

解を分離する

x_{1} = \frac{- ( - 174900 ) + 17490 0 ^{2} - 20226532984}{2 \cdot 85183}, x_{2} = \frac{- ( - 174900 ) - 17490 0 ^{2} - 20226532984}{2 \cdot 85183}

x = \frac{- ( - 174900 ) + 17490 0 ^{2} - 20226532984}{2 \cdot 85183} : \frac{174900 + 17490 0 ^{2} - 20226532984}{170366}

x = \frac{- ( - 174900 ) - 17490 0 ^{2} - 20226532984}{2 \cdot 85183} : \frac{174900 - 17490 0 ^{2} - 20226532984}{170366}

二次equationの解:

x = \frac{174900 + 17490 0 ^{2} - 20226532984}{170366}, x = \frac{174900 - 17490 0 ^{2} - 20226532984}{170366}
