x^{2} + 3 x + 9 = 0

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

Solution steps

x^{2} + 3 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

Simplify

3^{2} - 4 \cdot 1 \cdot 9 : 33 i

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

Separate the solutions

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

x = \frac{- 3 + 3 3 i}{2 \cdot 1} : - \frac{3}{2} + i \frac{3 3}{2}

x = \frac{- 3 - 3 3 i}{2 \cdot 1} : - \frac{3}{2} - i \frac{3 3}{2}

The solutions to the quadratic equation are:

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

lo g_{\frac{1}{5}} (3125)

- 3 (2 y + 7) = - 18

v^{2} - 6 v - 7 = 0

(n^{2})^{\frac{3}{2}}

∣ x + 4 ∣ = 5
