x^2-12x-1725=0

解

x^{2} - 12 x - 1725 = 0

解

x = 6 + 1761, x = 6 - 1761

+1

十進法表記

x = 47.96427 \dots, x = - 35.96427 \dots

解答ステップ

x^{2} - 12 x - 1725 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 1 \cdot ( - 1725 )}{2 \cdot 1}

(- 12)^{2} - 4 \cdot 1 \cdot (- 1725) = 21761

x_{1, 2} = \frac{- ( - 12 ) \pm 2 1761}{2 \cdot 1}

解を分離する

x_{1} = \frac{- ( - 12 ) + 2 1761}{2 \cdot 1}, x_{2} = \frac{- ( - 12 ) - 2 1761}{2 \cdot 1}

x = \frac{- ( - 12 ) + 2 1761}{2 \cdot 1} : 6 + 1761

x = \frac{- ( - 12 ) - 2 1761}{2 \cdot 1} : 6 - 1761

二次equationの解:

x = 6 + 1761, x = 6 - 1761
