4 x^{2} + 8 x + 5 = 0

x = - 1 + i \frac{1}{2}, x = - 1 - i \frac{1}{2}

Solution steps

4 x^{2} + 8 x + 5 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 4 \cdot 5}{2 \cdot 4}

Simplify

8^{2} - 4 \cdot 4 \cdot 5 : 4 i

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

Separate the solutions

x_{1} = \frac{- 8 + 4 i}{2 \cdot 4}, x_{2} = \frac{- 8 - 4 i}{2 \cdot 4}

x = \frac{- 8 + 4 i}{2 \cdot 4} : - 1 + i \frac{1}{2}

x = \frac{- 8 - 4 i}{2 \cdot 4} : - 1 - i \frac{1}{2}

The solutions to the quadratic equation are:

x = - 1 + i \frac{1}{2}, x = - 1 - i \frac{1}{2}

n^{2} - 22 n + 102 = 0

12 x^{2} - 520 x + 4000 = 0

x = 5 x^{2}

(x + 2)^{2} = 64

a^{2} = 9
