s^{2} + 5 s + 10 = 0

s = - \frac{5}{2} + i \frac{15}{2}, s = - \frac{5}{2} - i \frac{15}{2}

Solution steps

s^{2} + 5 s + 10 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 1 \cdot 10}{2 \cdot 1}

Simplify

5^{2} - 4 \cdot 1 \cdot 10 : 15 i

s_{1, 2} = \frac{- 5 \pm 15 i}{2 \cdot 1}

Separate the solutions

s_{1} = \frac{- 5 + 15 i}{2 \cdot 1}, s_{2} = \frac{- 5 - 15 i}{2 \cdot 1}

s = \frac{- 5 + 15 i}{2 \cdot 1} : - \frac{5}{2} + i \frac{15}{2}

s = \frac{- 5 - 15 i}{2 \cdot 1} : - \frac{5}{2} - i \frac{15}{2}

The solutions to the quadratic equation are:

s = - \frac{5}{2} + i \frac{15}{2}, s = - \frac{5}{2} - i \frac{15}{2}
