s^{2} - 8 s - 20 = 0

s = 10, s = - 2

Solution steps

s^{2} - 8 s - 20 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 1 \cdot ( - 20 )}{2 \cdot 1}

(- 8)^{2} - 4 \cdot 1 \cdot (- 20) = 12

s_{1, 2} = \frac{- ( - 8 ) \pm 12}{2 \cdot 1}

Separate the solutions

s_{1} = \frac{- ( - 8 ) + 12}{2 \cdot 1}, s_{2} = \frac{- ( - 8 ) - 12}{2 \cdot 1}

s = \frac{- ( - 8 ) + 12}{2 \cdot 1} : 10

s = \frac{- ( - 8 ) - 12}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

s = 10, s = - 2

25 x^{2} = 20 x - 4

14 x^{2} - 6 = 0

x^{2} - 10 x + 10 = - 5

x^{2} - 42 x + 8 = 0

x^{2} - 5 x - 31 = 5
