s^{2} + 6 s + 8.5 = 0

s = \frac{- 6 + 2}{2}, s = - \frac{6 + 2}{2}

Decimal Notation

s = - 2.29289 \dots, s = - 3.70710 \dots

Solution steps

s^{2} + 6 s + 8.5 = 0

Multiply both sides by

10

10 s^{2} + 60 s + 85 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- 60 \pm 6 0 ^{2} - 4 \cdot 10 \cdot 85}{2 \cdot 10}

6 0^{2} - 4 \cdot 10 \cdot 85 = 102

s_{1, 2} = \frac{- 60 \pm 10 2}{2 \cdot 10}

Separate the solutions

s_{1} = \frac{- 60 + 10 2}{2 \cdot 10}, s_{2} = \frac{- 60 - 10 2}{2 \cdot 10}

s = \frac{- 60 + 10 2}{2 \cdot 10} : \frac{- 6 + 2}{2}

s = \frac{- 60 - 10 2}{2 \cdot 10} : - \frac{6 + 2}{2}

The solutions to the quadratic equation are:

s = \frac{- 6 + 2}{2}, s = - \frac{6 + 2}{2}

\frac{p - 9}{3} = 2

2 b^{2} - 5 b - 3

8 x^{2} + 5 x = - 4

2 x + 5 + 2 x + 3 x = 9 x + 7

\frac{- 3 ( x + 3 )}{2} < 6
