8x^2-5x+3=0

解

8 x^{2} - 5 x + 3 = 0

解

x = \frac{5}{16} + i \frac{71}{16}, x = \frac{5}{16} - i \frac{71}{16}

解答ステップ

8 x^{2} - 5 x + 3 = 0

解くとthe二次式

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 8 \cdot 3}{2 \cdot 8}

簡素化

(- 5)^{2} - 4 \cdot 8 \cdot 3 : 71 i

x_{1, 2} = \frac{- ( - 5 ) \pm 71 i}{2 \cdot 8}

解を分離する

x_{1} = \frac{- ( - 5 ) + 71 i}{2 \cdot 8}, x_{2} = \frac{- ( - 5 ) - 71 i}{2 \cdot 8}

x = \frac{- ( - 5 ) + 71 i}{2 \cdot 8} : \frac{5}{16} + i \frac{71}{16}

x = \frac{- ( - 5 ) - 71 i}{2 \cdot 8} : \frac{5}{16} - i \frac{71}{16}

二次equationの解:

x = \frac{5}{16} + i \frac{71}{16}, x = \frac{5}{16} - i \frac{71}{16}
