(3)x=(x^2=9-3=5)

解

(3) x = (x^{2} = 9 - 3 = 5)

解

x = \frac{- ( - 3 ) + ( - 3 ) ^{2} - 4 = 9 ( - 3 = 5 )}{2 = 9}, x = \frac{- ( - 3 ) - ( - 3 ) ^{2} - 4 = 9 ( - 3 = 5 )}{2 = 9}

解答ステップ

(3) x = (x^{2} = 9 - 3 = 5)

改良

3 x = (x^{2} = 9 - 3 = 5)

辺を交換する

(x^{2} = 9 - 3 = 5) = 3 x

3 x

を左側に移動します

x^{2} = 9 - 3 = 5 - 3 x = 0

標準的な形式で書く

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

= 9 x^{2} - 3 x - 3 = 5 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 = 9 ( - 3 = 5 )}{2 = 9}

x = \frac{- ( - 3 ) + ( - 3 ) ^{2} - 4 = 9 ( - 3 = 5 )}{2 = 9}

x = \frac{- ( - 3 ) - ( - 3 ) ^{2} - 4 = 9 ( - 3 = 5 )}{2 = 9}

二次equationの解:

x = \frac{- ( - 3 ) + ( - 3 ) ^{2} - 4 = 9 ( - 3 = 5 )}{2 = 9}, x = \frac{- ( - 3 ) - ( - 3 ) ^{2} - 4 = 9 ( - 3 = 5 )}{2 = 9}

(2x-3)^2-(x+5)^2=0

(2 x - 3)^{2} - (x + 5)^{2} = 0

0.5x^2-3x=-x+2.5

0.5 x^{2} - 3 x = - x + 2.5

e = x^{2} - 3 x + 5

(10-x)(x/(4-3))=2

(10 - x) (\frac{x}{4 - 3}) = 2

\frac{x}{2} = \frac{( x ^{2} )}{7}
