5 x^{2} - 5 x - 1 = 0

x = \frac{5 + 3}{2 5}, x = \frac{5 - 3}{2 5}

Decimal Notation

x = 1.17082 \dots, x = - 0.17082 \dots

Solution steps

5 x^{2} - 5 x - 1 = 0

Solve with the quadratic formula

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

(- 5)^{2} - 4 \cdot 5 (- 1) = 35

x_{1, 2} = \frac{- ( - 5 ) \pm 3 5}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 3 5}{2 \cdot 5}, x_{2} = \frac{- ( - 5 ) - 3 5}{2 \cdot 5}

x = \frac{- ( - 5 ) + 3 5}{2 \cdot 5} : \frac{5 + 3}{2 5}

x = \frac{- ( - 5 ) - 3 5}{2 \cdot 5} : \frac{5 - 3}{2 5}

The solutions to the quadratic equation are:

x = \frac{5 + 3}{2 5}, x = \frac{5 - 3}{2 5}

7 x - 1 \leq - 50

- 3^{4}

- 6 x^{2} - 108 x - 510 = 0

x = \frac{12 \cdot 24}{2 ( 6 + 12 ) + 12 \cdot 6}

x^{2} + 5 x - 50
