x^{2} - 20 x - 20 = 0

x = 2 (5 + 30), x = 2 (5 - 30)

Decimal Notation

x = 20.95445 \dots, x = - 0.95445 \dots

Solution steps

x^{2} - 20 x - 20 = 0

Solve with the quadratic formula

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

(- 20)^{2} - 4 \cdot 1 \cdot (- 20) = 430

x_{1, 2} = \frac{- ( - 20 ) \pm 4 30}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 20 ) + 4 30}{2 \cdot 1}, x_{2} = \frac{- ( - 20 ) - 4 30}{2 \cdot 1}

x = \frac{- ( - 20 ) + 4 30}{2 \cdot 1} : 2 (5 + 30)

x = \frac{- ( - 20 ) - 4 30}{2 \cdot 1} : 2 (5 - 30)

The solutions to the quadratic equation are:

x = 2 (5 + 30), x = 2 (5 - 30)

x^{\frac{1}{2}} \cdot 2 x

2 w^{2} + w + 1 = 0

\frac{5}{6} \cdot 7

2 x^{2} + 4 x + 1 = 0

2^{2^{3}}
