solvefor x,Cx^2+x+y^2=0

解

解く

x, C x^{2} + x + y^{2} = 0

解

x = \frac{- 1 + 1 - 4 C y ^{2}}{2 C}, x = \frac{- 1 - 1 - 4 C y ^{2}}{2 C}; C \neq = 0

解答ステップ

C x^{2} + x + y^{2} = 0

解くとthe二次式

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 C y ^{2}}{2 C}

簡素化

1^{2} - 4 C y^{2} : 1 - 4 C y^{2}

x_{1, 2} = \frac{- 1 \pm 1 - 4 C y ^{2}}{2 C}; C \neq = 0

解を分離する

x_{1} = \frac{- 1 + 1 - 4 C y ^{2}}{2 C}, x_{2} = \frac{- 1 - 1 - 4 C y ^{2}}{2 C}

x = \frac{- 1 + 1 - 4 C y ^{2}}{2 C}; C \neq = 0

x = \frac{- 1 - 1 - 4 C y ^{2}}{2 C}; C \neq = 0

二次equationの解:

x = \frac{- 1 + 1 - 4 C y ^{2}}{2 C}, x = \frac{- 1 - 1 - 4 C y ^{2}}{2 C}; C \neq = 0

x^{2} - 8 x + 16 = - 12

solvefor x,f(x+2)=x^2-3x+2

so l v e f or x, f (x + 2) = x^{2} - 3 x + 2

(k+1)x^2-(k-1)x-(k+2)=0

(k + 1) x^{2} - (k - 1) x - (k + 2) = 0

0 = x^{2} - 36

(x - 3) 2 x = 0
