quadraticformula x^2-24=0

解

x^{2} - 24 = 0

x = 26, x = - 26

十進法表記

x = 4.89897 \dots, x = - 4.89897 \dots

解答ステップ

x^{2} - 24 = 0

解くとthe二次式

x_{1, 2} = \frac{- 0 \pm 0 ^{2} - 4 \cdot 1 \cdot ( - 24 )}{2 \cdot 1}

0^{2} - 4 \cdot 1 \cdot (- 24) = 46

x_{1, 2} = \frac{- 0 \pm 4 6}{2 \cdot 1}

解を分離する

x_{1} = \frac{- 0 + 4 6}{2 \cdot 1}, x_{2} = \frac{- 0 - 4 6}{2 \cdot 1}

x = \frac{- 0 + 4 6}{2 \cdot 1} : 26

x = \frac{- 0 - 4 6}{2 \cdot 1} : - 26

二次equationの解:

x = 26, x = - 26
