(x+4)^2-3(x+4)-3=0

解

(x + 4)^{2} - 3 (x + 4) - 3 = 0

解

x = \frac{- 5 + 21}{2}, x = \frac{- 5 - 21}{2}

+1

十進法表記

x = - 0.20871 \dots, x = - 4.79128 \dots

解答ステップ

(x + 4)^{2} - 3 (x + 4) - 3 = 0

拡張

(x + 4)^{2} - 3 (x + 4) - 3 : x^{2} + 5 x + 1

x^{2} + 5 x + 1 = 0

解くとthe二次式

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 1 \cdot 1}{2 \cdot 1}

5^{2} - 4 \cdot 1 \cdot 1 = 21

x_{1, 2} = \frac{- 5 \pm 21}{2 \cdot 1}

解を分離する

x_{1} = \frac{- 5 + 21}{2 \cdot 1}, x_{2} = \frac{- 5 - 21}{2 \cdot 1}

x = \frac{- 5 + 21}{2 \cdot 1} : \frac{- 5 + 21}{2}

x = \frac{- 5 - 21}{2 \cdot 1} : \frac{- 5 - 21}{2}

二次equationの解:

x = \frac{- 5 + 21}{2}, x = \frac{- 5 - 21}{2}
