x^{2} - 9 x + 5 = 0

x = \frac{9 + 61}{2}, x = \frac{9 - 61}{2}

Solution steps

x^{2} - 9 x + 5 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 1 \cdot 5}{2 \cdot 1}

(- 9)^{2} - 4 \cdot 1 \cdot 5 = 61

x_{1, 2} = \frac{- ( - 9 ) \pm 61}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 61}{2 \cdot 1}, x_{2} = \frac{- ( - 9 ) - 61}{2 \cdot 1}

x = \frac{- ( - 9 ) + 61}{2 \cdot 1} : \frac{9 + 61}{2}

x = \frac{- ( - 9 ) - 61}{2 \cdot 1} : \frac{9 - 61}{2}

The solutions to the quadratic equation are:

x = \frac{9 + 61}{2}, x = \frac{9 - 61}{2}
