2 x^{2} + 8 x + 11 = 0

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

Solution steps

2 x^{2} + 8 x + 11 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 2 \cdot 11}{2 \cdot 2}

Simplify

8^{2} - 4 \cdot 2 \cdot 11 : 26 i

x_{1, 2} = \frac{- 8 \pm 2 6 i}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 8 + 2 6 i}{2 \cdot 2}, x_{2} = \frac{- 8 - 2 6 i}{2 \cdot 2}

x = \frac{- 8 + 2 6 i}{2 \cdot 2} : - 2 + i \frac{3}{2}

x = \frac{- 8 - 2 6 i}{2 \cdot 2} : - 2 - i \frac{3}{2}

The solutions to the quadratic equation are:

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

x^{2} = x + 30
