sqrt(3)*x^2+10x+7sqrt(3)=0

解

3 \cdot x^{2} + 10 x + 73 = 0

x = - 3, x = - \frac{7}{3}

十進法表記

x = - 1.73205 \dots, x = - 4.04145 \dots

解答ステップ

3 x^{2} + 10 x + 73 = 0

解くとthe二次式

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 3 \cdot 7 3}{2 3}

1 0^{2} - 43 \cdot 73 = 4

x_{1, 2} = \frac{- 10 \pm 4}{2 3}

解を分離する

x_{1} = \frac{- 10 + 4}{2 3}, x_{2} = \frac{- 10 - 4}{2 3}

x = \frac{- 10 + 4}{2 3} : - 3

x = \frac{- 10 - 4}{2 3} : - \frac{7}{3}

二次equationの解:

x = - 3, x = - \frac{7}{3}
