3/1+x-x^2+1/1-x^2+x+1/1-x=0

解

\frac{3}{1} + x - x^{2} + \frac{1}{1} - x^{2} + x + \frac{1}{1} - x = 0

解

x = - \frac{- 1 + 41}{4}, x = \frac{1 + 41}{4}

+1

十進法表記

x = - 1.35078 \dots, x = 1.85078 \dots

解答ステップ

\frac{3}{1} + x - x^{2} + \frac{1}{1} - x^{2} + x + \frac{1}{1} - x = 0

拡張

\frac{3}{1} + x - x^{2} + \frac{1}{1} - x^{2} + x + \frac{1}{1} - x : - 2 x^{2} + x + 5

- 2 x^{2} + x + 5 = 0

解くとthe二次式

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 ( - 2 ) \cdot 5}{2 ( - 2 )}

1^{2} - 4 (- 2) \cdot 5 = 41

x_{1, 2} = \frac{- 1 \pm 41}{2 ( - 2 )}

解を分離する

x_{1} = \frac{- 1 + 41}{2 ( - 2 )}, x_{2} = \frac{- 1 - 41}{2 ( - 2 )}

x = \frac{- 1 + 41}{2 ( - 2 )} : - \frac{- 1 + 41}{4}

x = \frac{- 1 - 41}{2 ( - 2 )} : \frac{1 + 41}{4}

二次equationの解:

x = - \frac{- 1 + 41}{4}, x = \frac{1 + 41}{4}

\frac{x}{3} = \frac{x ^{2}}{5}

x^{2} + 2 a - 15 = 0

9x^2-60x+(a^2+b^2)=0

9 x^{2} - 60 x + (a^{2} + b^{2}) = 0

solvefor x,y^4=c*x^2

so l v e f or x, y^{4} = c \cdot x^{2}

(x+2)^3=x(x^2-1)

(x + 2)^{3} = x (x^{2} - 1)
