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

x = - \frac{3}{4} + i \frac{55}{4}, x = - \frac{3}{4} - i \frac{55}{4}

Solution steps

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

Solve with the quadratic formula

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

Simplify

3^{2} - 4 \cdot 2 \cdot 8 : 55 i

x_{1, 2} = \frac{- 3 \pm 55 i}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 3 + 55 i}{2 \cdot 2}, x_{2} = \frac{- 3 - 55 i}{2 \cdot 2}

x = \frac{- 3 + 55 i}{2 \cdot 2} : - \frac{3}{4} + i \frac{55}{4}

x = \frac{- 3 - 55 i}{2 \cdot 2} : - \frac{3}{4} - i \frac{55}{4}

The solutions to the quadratic equation are:

x = - \frac{3}{4} + i \frac{55}{4}, x = - \frac{3}{4} - i \frac{55}{4}

5 x + 30 y

\frac{2}{3} + \frac{1}{4}

\frac{c ^{2} - 9}{2 c + 6}

4 x^{2} - 12 x y + 5 y^{2}

4 x^{2} - 64 = 0
