x^{2} - 9 x - 8 = 0

x = \frac{9 + 113}{2}, x = \frac{9 - 113}{2}

Decimal Notation

x = 9.81507 \dots, x = - 0.81507 \dots

Solution steps

x^{2} - 9 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 1 \cdot ( - 8 )}{2 \cdot 1}

(- 9)^{2} - 4 \cdot 1 \cdot (- 8) = 113

x_{1, 2} = \frac{- ( - 9 ) \pm 113}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 113}{2 \cdot 1}, x_{2} = \frac{- ( - 9 ) - 113}{2 \cdot 1}

x = \frac{- ( - 9 ) + 113}{2 \cdot 1} : \frac{9 + 113}{2}

x = \frac{- ( - 9 ) - 113}{2 \cdot 1} : \frac{9 - 113}{2}

The solutions to the quadratic equation are:

x = \frac{9 + 113}{2}, x = \frac{9 - 113}{2}

y^{2} - 6 y + 7 = 0

2 q^{2} - 16 q = - 73

4 m^{2} - 5 m - 1 = 2 m

18 x^{2} - 24 x = 0

2 y^{2} - 2 y - 10 = 1
