44.118x^2-401.28x+182.568=0

解

44.118 x^{2} - 401.28 x + 182.568 = 0

解

x = \frac{401280 + 40128 0 ^{2} - 32218140096}{88236}, x = \frac{401280 - 40128 0 ^{2} - 32218140096}{88236}

+1

十進法表記

x = 8.61527 \dots, x = 0.48032 \dots

解答ステップ

44.118 x^{2} - 401.28 x + 182.568 = 0

以下で両辺を乗じる:

1000

44118 x^{2} - 401280 x + 182568 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 401280 ) \pm ( - 401280 ) ^{2} - 4 \cdot 44118 \cdot 182568}{2 \cdot 44118}

(- 401280)^{2} - 4 \cdot 44118 \cdot 182568 = 40128 0^{2} - 32218140096

x_{1, 2} = \frac{- ( - 401280 ) \pm 40128 0 ^{2} - 32218140096}{2 \cdot 44118}

解を分離する

x_{1} = \frac{- ( - 401280 ) + 40128 0 ^{2} - 32218140096}{2 \cdot 44118}, x_{2} = \frac{- ( - 401280 ) - 40128 0 ^{2} - 32218140096}{2 \cdot 44118}

x = \frac{- ( - 401280 ) + 40128 0 ^{2} - 32218140096}{2 \cdot 44118} : \frac{401280 + 40128 0 ^{2} - 32218140096}{88236}

x = \frac{- ( - 401280 ) - 40128 0 ^{2} - 32218140096}{2 \cdot 44118} : \frac{401280 - 40128 0 ^{2} - 32218140096}{88236}

二次equationの解:

x = \frac{401280 + 40128 0 ^{2} - 32218140096}{88236}, x = \frac{401280 - 40128 0 ^{2} - 32218140096}{88236}
