(x+6)^2=x^2+x^2

解

(x + 6)^{2} = x^{2} + x^{2}

解

x = - 6 (2 - 1), x = 6 (1 + 2)

+1

十進法表記

x = - 2.48528 \dots, x = 14.48528 \dots

解答ステップ

(x + 6)^{2} = x^{2} + x^{2}

拡張

(x + 6)^{2} : x^{2} + 12 x + 36

x^{2} + 12 x + 36 = 2 x^{2}

2 x^{2}

- x^{2} + 12 x + 36 = 0

解くとthe二次式

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 ( - 1 ) \cdot 36}{2 ( - 1 )}

1 2^{2} - 4 (- 1) \cdot 36 = 122

x_{1, 2} = \frac{- 12 \pm 12 2}{2 ( - 1 )}

解を分離する

x_{1} = \frac{- 12 + 12 2}{2 ( - 1 )}, x_{2} = \frac{- 12 - 12 2}{2 ( - 1 )}

x = \frac{- 12 + 12 2}{2 ( - 1 )} : - 6 (2 - 1)

x = \frac{- 12 - 12 2}{2 ( - 1 )} : 6 (1 + 2)

二次equationの解:

x = - 6 (2 - 1), x = 6 (1 + 2)
