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

解

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

解

x = \frac{1}{2}, x = 1

+1

十進法表記

x = 0.5, x = 1

解答ステップ

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

解くとthe二次式

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 ( - 2 ) ( - 1 )}{2 ( - 2 )}

3^{2} - 4 (- 2) (- 1) = 1

x_{1, 2} = \frac{- 3 \pm 1}{2 ( - 2 )}

解を分離する

x_{1} = \frac{- 3 + 1}{2 ( - 2 )}, x_{2} = \frac{- 3 - 1}{2 ( - 2 )}

x = \frac{- 3 + 1}{2 ( - 2 )} : \frac{1}{2}

x = \frac{- 3 - 1}{2 ( - 2 )} : 1

二次equationの解:

x = \frac{1}{2}, x = 1

solvefor x,x^2+5x+y^2-y+7=0

so l v e f or x, x^{2} + 5 x + y^{2} - y + 7 = 0

-5p^2+8p-8=-6p^2

- 5 p^{2} + 8 p - 8 = - 6 p^{2}

12 x^{2} - 24 x + 8 = 0

solvefor x,9x^2+4xy+6y^2+12x+36y+44=0

so l v e f or x, 9 x^{2} + 4 x y + 6 y^{2} + 12 x + 36 y + 44 = 0

0 = x^{2} - 6 x + 10
