x^{2} - 10 x - 9 = 0

x = 5 + 34, x = 5 - 34

Decimal Notation

x = 10.83095 \dots, x = - 0.83095 \dots

Solution steps

x^{2} - 10 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 1 \cdot ( - 9 )}{2 \cdot 1}

(- 10)^{2} - 4 \cdot 1 \cdot (- 9) = 234

x_{1, 2} = \frac{- ( - 10 ) \pm 2 34}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 10 ) + 2 34}{2 \cdot 1}, x_{2} = \frac{- ( - 10 ) - 2 34}{2 \cdot 1}

x = \frac{- ( - 10 ) + 2 34}{2 \cdot 1} : 5 + 34

x = \frac{- ( - 10 ) - 2 34}{2 \cdot 1} : 5 - 34

The solutions to the quadratic equation are:

x = 5 + 34, x = 5 - 34

z^{2} - 3 z - 10

(x - 2) (3 x + 5) = 0
