2 x^{2} - 8 x + 4 = 0

x = 2 + 2, x = 2 - 2

Decimal Notation

x = 3.41421 \dots, x = 0.58578 \dots

Solution steps

2 x^{2} - 8 x + 4 = 0

Solve with the quadratic formula

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

(- 8)^{2} - 4 \cdot 2 \cdot 4 = 42

x_{1, 2} = \frac{- ( - 8 ) \pm 4 2}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 4 2}{2 \cdot 2}, x_{2} = \frac{- ( - 8 ) - 4 2}{2 \cdot 2}

x = \frac{- ( - 8 ) + 4 2}{2 \cdot 2} : 2 + 2

x = \frac{- ( - 8 ) - 4 2}{2 \cdot 2} : 2 - 2

The solutions to the quadratic equation are:

x = 2 + 2, x = 2 - 2

- 3 ∣ p ∣ = - 12

- 4 x - 14 - 9 x = - 13 x - 7 - 6
