x^{2} - 7 x - 10 = 8

x = 9, x = - 2

Solution steps

x^{2} - 7 x - 10 = 8

Move

8

to the left side

x^{2} - 7 x - 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot ( - 18 )}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot (- 18) = 11

x_{1, 2} = \frac{- ( - 7 ) \pm 11}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 11}{2 \cdot 1}, x_{2} = \frac{- ( - 7 ) - 11}{2 \cdot 1}

x = \frac{- ( - 7 ) + 11}{2 \cdot 1} : 9

x = \frac{- ( - 7 ) - 11}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

x = 9, x = - 2

x^{2} - 9 x + 13 = 0

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

x^{2} - 6 x - 16 = 0

24 x - 36 x^{2} = 0

x^{2} - x - 30 = 0
