5 s^{2} + 8 s - 8 = 0

s = \frac{2 ( 14 - 2 )}{5}, s = - \frac{2 ( 2 + 14 )}{5}

Decimal Notation

s = 0.69666 \dots, s = - 2.29666 \dots

Solution steps

5 s^{2} + 8 s - 8 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 5 ( - 8 )}{2 \cdot 5}

8^{2} - 4 \cdot 5 (- 8) = 414

s_{1, 2} = \frac{- 8 \pm 4 14}{2 \cdot 5}

Separate the solutions

s_{1} = \frac{- 8 + 4 14}{2 \cdot 5}, s_{2} = \frac{- 8 - 4 14}{2 \cdot 5}

s = \frac{- 8 + 4 14}{2 \cdot 5} : \frac{2 ( 14 - 2 )}{5}

s = \frac{- 8 - 4 14}{2 \cdot 5} : - \frac{2 ( 2 + 14 )}{5}

The solutions to the quadratic equation are:

s = \frac{2 ( 14 - 2 )}{5}, s = - \frac{2 ( 2 + 14 )}{5}

r, r^{2} = θ

36 = - 4 x^{2} - 50

x, x^{2} - 8 x y + 25 y^{2} = 81

x^{2} = 2025

5.9 x^{2} + 3 x - 2.7 = 0
