0=0.8796429+37.30054x-39.26339x^2

解

0 = 0.8796429 + 37.30054 x - 39.26339 x^{2}

解

x = - \frac{- 37.30054 + 1529.48133 \dots}{78.52678}, x = \frac{37.30054 + 1529.48133 \dots}{78.52678}

+1

十進法表記

x = - 0.02302 \dots, x = 0.97303 \dots

解答ステップ

0 = 0.8796429 + 37.30054 x - 39.26339 x^{2}

辺を交換する

0.8796429 + 37.30054 x - 39.26339 x^{2} = 0

標準的な形式で書く

a x^{2} + b x + c = 0

- 39.26339 x^{2} + 37.30054 x + 0.8796429 = 0

解くとthe二次式

x_{1, 2} = \frac{- 37.30054 \pm 37.3005 4 ^{2} - 4 ( - 39.26339 ) \cdot 0.8796429}{2 ( - 39.26339 )}

37.3005 4^{2} - 4 (- 39.26339) \cdot 0.8796429 = 1529.48133 \dots

x_{1, 2} = \frac{- 37.30054 \pm 1529.48133 \dots}{2 ( - 39.26339 )}

解を分離する

x_{1} = \frac{- 37.30054 + 1529.48133 \dots}{2 ( - 39.26339 )}, x_{2} = \frac{- 37.30054 - 1529.48133 \dots}{2 ( - 39.26339 )}

x = \frac{- 37.30054 + 1529.48133 \dots}{2 ( - 39.26339 )} : - \frac{- 37.30054 + 1529.48133 \dots}{78.52678}

x = \frac{- 37.30054 - 1529.48133 \dots}{2 ( - 39.26339 )} : \frac{37.30054 + 1529.48133 \dots}{78.52678}

二次equationの解:

x = - \frac{- 37.30054 + 1529.48133 \dots}{78.52678}, x = \frac{37.30054 + 1529.48133 \dots}{78.52678}
