4x^2-48x+144=0

解

4 x^{2} - 48 x + 144 = 0

x = 6

解答ステップ

4 x^{2} - 48 x + 144 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 48 ) \pm ( - 48 ) ^{2} - 4 \cdot 4 \cdot 144}{2 \cdot 4}

(- 48)^{2} - 4 \cdot 4 \cdot 144 = 0

x_{1, 2} = \frac{- ( - 48 ) \pm 0}{2 \cdot 4}

x = \frac{- ( - 48 )}{2 \cdot 4}

\frac{- ( - 48 )}{2 \cdot 4} = 6

x = 6

二次equationの解:

x = 6
