8x^2+3-6x=5x^2

解

8 x^{2} + 3 - 6 x = 5 x^{2}

x = 1

解答ステップ

8 x^{2} + 3 - 6 x = 5 x^{2}

5 x^{2}

3 x^{2} - 6 x + 3 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 3 \cdot 3}{2 \cdot 3}

(- 6)^{2} - 4 \cdot 3 \cdot 3 = 0

x_{1, 2} = \frac{- ( - 6 ) \pm 0}{2 \cdot 3}

x = \frac{- ( - 6 )}{2 \cdot 3}

\frac{- ( - 6 )}{2 \cdot 3} = 1

x = 1

二次equationの解:

x = 1
