2 x^{2} + 3 x + 15 = 0

x = - \frac{3}{4} + i \frac{111}{4}, x = - \frac{3}{4} - i \frac{111}{4}

Solution steps

2 x^{2} + 3 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 2 \cdot 15}{2 \cdot 2}

Simplify

3^{2} - 4 \cdot 2 \cdot 15 : 111 i

x_{1, 2} = \frac{- 3 \pm 111 i}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 3 + 111 i}{2 \cdot 2}, x_{2} = \frac{- 3 - 111 i}{2 \cdot 2}

x = \frac{- 3 + 111 i}{2 \cdot 2} : - \frac{3}{4} + i \frac{111}{4}

x = \frac{- 3 - 111 i}{2 \cdot 2} : - \frac{3}{4} - i \frac{111}{4}

The solutions to the quadratic equation are:

x = - \frac{3}{4} + i \frac{111}{4}, x = - \frac{3}{4} - i \frac{111}{4}
