s^{2} + 8 s + 15 = 0

s = - 3, s = - 5

Solution steps

s^{2} + 8 s + 15 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot 15}{2 \cdot 1}

8^{2} - 4 \cdot 1 \cdot 15 = 2

s_{1, 2} = \frac{- 8 \pm 2}{2 \cdot 1}

Separate the solutions

s_{1} = \frac{- 8 + 2}{2 \cdot 1}, s_{2} = \frac{- 8 - 2}{2 \cdot 1}

s = \frac{- 8 + 2}{2 \cdot 1} : - 3

s = \frac{- 8 - 2}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

s = - 3, s = - 5

x - 5 = 12

4 s^{2} + 36 s + 81 = 0

(x + 3) (x + 4) = 0

3 ∣ 2 x - 5 ∣ = 15

\frac{7}{22} \cdot \frac{33}{9} + \frac{10}{11}
