-2.3214x^2+12.786x+332.86=289

解

- 2.3214 x^{2} + 12.786 x + 332.86 = 289

解

x = - \frac{- 12.786 + 570.748212}{4.6428}, x = \frac{12.786 + 570.748212}{4.6428}

+1

十進法表記

- 2.3214 x^{2} + 12.786 x + 43.86 = 0

解くとthe二次式

x_{1, 2} = \frac{- 12.786 \pm 12.78 6 ^{2} - 4 ( - 2.3214 ) \cdot 43.86}{2 ( - 2.3214 )}

12.78 6^{2} - 4 (- 2.3214) \cdot 43.86 = 570.748212

x_{1, 2} = \frac{- 12.786 \pm 570.748212}{2 ( - 2.3214 )}

解を分離する

x_{1} = \frac{- 12.786 + 570.748212}{2 ( - 2.3214 )}, x_{2} = \frac{- 12.786 - 570.748212}{2 ( - 2.3214 )}

x = \frac{- 12.786 + 570.748212}{2 ( - 2.3214 )} : - \frac{- 12.786 + 570.748212}{4.6428}

x = \frac{- 12.786 - 570.748212}{2 ( - 2.3214 )} : \frac{12.786 + 570.748212}{4.6428}

二次equationの解:

x = - \frac{- 12.786 + 570.748212}{4.6428}, x = \frac{12.786 + 570.748212}{4.6428}
