s^{2} - 4 s + 2 = 0

s = 2 + 2, s = 2 - 2

Decimal Notation

s = 3.41421 \dots, s = 0.58578 \dots

Solution steps

s^{2} - 4 s + 2 = 0

Solve with the quadratic formula

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

(- 4)^{2} - 4 \cdot 1 \cdot 2 = 22

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

Separate the solutions

s_{1} = \frac{- ( - 4 ) + 2 2}{2 \cdot 1}, s_{2} = \frac{- ( - 4 ) - 2 2}{2 \cdot 1}

s = \frac{- ( - 4 ) + 2 2}{2 \cdot 1} : 2 + 2

s = \frac{- ( - 4 ) - 2 2}{2 \cdot 1} : 2 - 2

The solutions to the quadratic equation are:

s = 2 + 2, s = 2 - 2
