3 x^{2} + 9 x + 8 = 0

x = - \frac{3}{2} + i \frac{15}{6}, x = - \frac{3}{2} - i \frac{15}{6}

Solution steps

3 x^{2} + 9 x + 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 3 \cdot 8}{2 \cdot 3}

Simplify

9^{2} - 4 \cdot 3 \cdot 8 : 15 i

x_{1, 2} = \frac{- 9 \pm 15 i}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 9 + 15 i}{2 \cdot 3}, x_{2} = \frac{- 9 - 15 i}{2 \cdot 3}

x = \frac{- 9 + 15 i}{2 \cdot 3} : - \frac{3}{2} + i \frac{15}{6}

x = \frac{- 9 - 15 i}{2 \cdot 3} : - \frac{3}{2} - i \frac{15}{6}

The solutions to the quadratic equation are:

x = - \frac{3}{2} + i \frac{15}{6}, x = - \frac{3}{2} - i \frac{15}{6}

x^{2} + 19 = - 12 x

2 m^{2} + 14 + 8 m = 0

- x^{2} + 9 x - 16 = 0

3 (2 x^{2} + 7) = - 87

y^{2} - 7 y = 0
