x^{2} - 9 x = - 8

x = 8, x = 1

Solution steps

x^{2} - 9 x = - 8

Move

8

to the left side

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 = 7

x_{1, 2} = \frac{- ( - 9 ) \pm 7}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 7}{2 \cdot 1}, x_{2} = \frac{- ( - 9 ) - 7}{2 \cdot 1}

x = \frac{- ( - 9 ) + 7}{2 \cdot 1} : 8

x = \frac{- ( - 9 ) - 7}{2 \cdot 1} : 1

The solutions to the quadratic equation are:

x = 8, x = 1
