s, s^{2} + 4 s + 5 = 0

s = - 2 + i, s = - 2 - i

Solution steps

s^{2} + 4 s + 5 = 0

Solve with the quadratic formula

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

Simplify

4^{2} - 4 \cdot 1 \cdot 5 : 2 i

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

s = - 2 + i, s = - 2 - i

(30 + x) \cdot (30 + x) = 1660

x \cdot x + 1 \cdot x + 2 = (x + 1) 80

x^{2} + 160 x + 10000 = 0

x, 3 x^{2} - 4 x + 2 = 0

4 x^{2} + 17 x = 6 x - 2 x^{2}
