x^{2} + 18 x + 130 = 0

x = - 9 + 7 i, x = - 9 - 7 i

Solution steps

x^{2} + 18 x + 130 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 \cdot 1 \cdot 130}{2 \cdot 1}

Simplify

1 8^{2} - 4 \cdot 1 \cdot 130 : 14 i

x_{1, 2} = \frac{- 18 \pm 14 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 18 + 14 i}{2 \cdot 1}, x_{2} = \frac{- 18 - 14 i}{2 \cdot 1}

x = \frac{- 18 + 14 i}{2 \cdot 1} : - 9 + 7 i

x = \frac{- 18 - 14 i}{2 \cdot 1} : - 9 - 7 i

The solutions to the quadratic equation are:

x = - 9 + 7 i, x = - 9 - 7 i

∣ 3 x + 2 ∣ \geq 1
