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

x = - \frac{1}{4} + i \frac{15}{4}, x = - \frac{1}{4} - i \frac{15}{4}

Solution steps

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

Solve with the quadratic formula

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

Simplify

1^{2} - 4 \cdot 2 \cdot 2 : 15 i

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

Separate the solutions

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

x = \frac{- 1 + 15 i}{2 \cdot 2} : - \frac{1}{4} + i \frac{15}{4}

x = \frac{- 1 - 15 i}{2 \cdot 2} : - \frac{1}{4} - i \frac{15}{4}

The solutions to the quadratic equation are:

x = - \frac{1}{4} + i \frac{15}{4}, x = - \frac{1}{4} - i \frac{15}{4}
