51+769/32x-1/210*(x)^2=0

解

51 + \frac{769}{32} \cdot x - \frac{1}{2} \cdot 10 \cdot (x)^{2} = 0

解

x = - \frac{51}{32}, x = \frac{32}{5}

+1

十進法表記

x = - 1.59375, x = 6.4

解答ステップ

51 + \frac{769}{32} x - \frac{1}{2} \cdot 10 x^{2} = 0

以下の最小公倍数を求める:

32, 2 : 32

以下で乗じる: LCM=

32

51 \cdot 32 + \frac{769}{32} x \cdot 32 - \frac{1}{2} \cdot 10 x^{2} \cdot 32 = 0 \cdot 32

簡素化

- 160 x^{2} + 769 x + 1632 = 0

解くとthe二次式

x_{1, 2} = \frac{- 769 \pm 76 9 ^{2} - 4 ( - 160 ) \cdot 1632}{2 ( - 160 )}

76 9^{2} - 4 (- 160) \cdot 1632 = 1279

x_{1, 2} = \frac{- 769 \pm 1279}{2 ( - 160 )}

解を分離する

x_{1} = \frac{- 769 + 1279}{2 ( - 160 )}, x_{2} = \frac{- 769 - 1279}{2 ( - 160 )}

x = \frac{- 769 + 1279}{2 ( - 160 )} : - \frac{51}{32}

x = \frac{- 769 - 1279}{2 ( - 160 )} : \frac{32}{5}

二次equationの解:

x = - \frac{51}{32}, x = \frac{32}{5}
