2 x^{2} + 4 x + 30 = 0

x = - 1 + 14 i, x = - 1 - 14 i

Solution steps

2 x^{2} + 4 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 \cdot 2 \cdot 30}{2 \cdot 2}

Simplify

4^{2} - 4 \cdot 2 \cdot 30 : 414 i

x_{1, 2} = \frac{- 4 \pm 4 14 i}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 4 + 4 14 i}{2 \cdot 2}, x_{2} = \frac{- 4 - 4 14 i}{2 \cdot 2}

x = \frac{- 4 + 4 14 i}{2 \cdot 2} : - 1 + 14 i

x = \frac{- 4 - 4 14 i}{2 \cdot 2} : - 1 - 14 i

The solutions to the quadratic equation are:

x = - 1 + 14 i, x = - 1 - 14 i

x^{2} + 2 x - 0.5 = 0

(x + 2)^{2} + x^{2} = 74

(3 y + 17)^{2} = 50

w^{2} = 8 (w - 4)

a, a b^{2} + a^{2} b + 3 = ab
