x^2-58x+741=0

解

x^{2} - 58 x + 741 = 0

x = 39, x = 19

解答ステップ

x^{2} - 58 x + 741 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 58 ) \pm ( - 58 ) ^{2} - 4 \cdot 1 \cdot 741}{2 \cdot 1}

(- 58)^{2} - 4 \cdot 1 \cdot 741 = 20

x_{1, 2} = \frac{- ( - 58 ) \pm 20}{2 \cdot 1}

解を分離する

x_{1} = \frac{- ( - 58 ) + 20}{2 \cdot 1}, x_{2} = \frac{- ( - 58 ) - 20}{2 \cdot 1}

x = \frac{- ( - 58 ) + 20}{2 \cdot 1} : 39

x = \frac{- ( - 58 ) - 20}{2 \cdot 1} : 19

二次equationの解:

x = 39, x = 19
