(k-12)x^2+2(k-12)x+2=0

解

(k - 12) \cdot x^{2} + 2 (k - 12) \cdot x + 2 = 0

解

x = \frac{- k + 12 + k ^{2} - 26 k + 168}{k - 12}, x = \frac{- k + 12 - k ^{2} - 26 k + 168}{k - 12}; k \neq = 12

解答ステップ

(k - 12) x^{2} + 2 (k - 12) x + 2 = 0

拡張

(k - 12) x^{2} + 2 (k - 12) x + 2 : k x^{2} - 12 x^{2} + 2 k x - 24 x + 2

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

標準的な形式で書く

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

(k - 12) x^{2} + (2 k - 24) x + 2 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( 2 k - 24 ) \pm ( 2 k - 24 ) ^{2} - 4 ( k - 12 ) \cdot 2}{2 ( k - 12 )}

簡素化

(2 k - 24)^{2} - 4 (k - 12) \cdot 2 : 2 k^{2} - 26 k + 168

x_{1, 2} = \frac{- ( 2 k - 24 ) \pm 2 k ^{2} - 26 k + 168}{2 ( k - 12 )}; k \neq = 12

解を分離する

x_{1} = \frac{- ( 2 k - 24 ) + 2 k ^{2} - 26 k + 168}{2 ( k - 12 )}, x_{2} = \frac{- ( 2 k - 24 ) - 2 k ^{2} - 26 k + 168}{2 ( k - 12 )}

x = \frac{- ( 2 k - 24 ) + 2 k ^{2} - 26 k + 168}{2 ( k - 12 )} : \frac{- k + 12 + k ^{2} - 26 k + 168}{k - 12}

x = \frac{- ( 2 k - 24 ) - 2 k ^{2} - 26 k + 168}{2 ( k - 12 )} : \frac{- k + 12 - k ^{2} - 26 k + 168}{k - 12}

二次equationの解:

x = \frac{- k + 12 + k ^{2} - 26 k + 168}{k - 12}, x = \frac{- k + 12 - k ^{2} - 26 k + 168}{k - 12}; k \neq = 12
