- 8 x^{2} + 3 x - 7 = 0

x = \frac{3}{16} - i \frac{215}{16}, x = \frac{3}{16} + i \frac{215}{16}

Solution steps

- 8 x^{2} + 3 x - 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 ( - 8 ) ( - 7 )}{2 ( - 8 )}

Simplify

3^{2} - 4 (- 8) (- 7) : 215 i

x_{1, 2} = \frac{- 3 \pm 215 i}{2 ( - 8 )}

Separate the solutions

x_{1} = \frac{- 3 + 215 i}{2 ( - 8 )}, x_{2} = \frac{- 3 - 215 i}{2 ( - 8 )}

x = \frac{- 3 + 215 i}{2 ( - 8 )} : \frac{3}{16} - i \frac{215}{16}

x = \frac{- 3 - 215 i}{2 ( - 8 )} : \frac{3}{16} + i \frac{215}{16}

The solutions to the quadratic equation are:

x = \frac{3}{16} - i \frac{215}{16}, x = \frac{3}{16} + i \frac{215}{16}

2 x^{2} - 6 = 4 x

- 12 x + 7 = 5 - 2 x^{2}

s^{2} = 0

r^{2} + 4 r + 8 = 0

x^{2} - 16 x + 45 = 0
