x^{2} - 10 x - 67 = 8

x = 15, x = - 5

Solution steps

x^{2} - 10 x - 67 = 8

Move

8

to the left side

x^{2} - 10 x - 75 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 1 \cdot ( - 75 )}{2 \cdot 1}

(- 10)^{2} - 4 \cdot 1 \cdot (- 75) = 20

x_{1, 2} = \frac{- ( - 10 ) \pm 20}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 10 ) + 20}{2 \cdot 1}, x_{2} = \frac{- ( - 10 ) - 20}{2 \cdot 1}

x = \frac{- ( - 10 ) + 20}{2 \cdot 1} : 15

x = \frac{- ( - 10 ) - 20}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = 15, x = - 5

x, 4 x^{2} + y^{2} + z^{2} - 8 x = 0

x, x^{2} + x = 6

r^{2} - 10 r + 9 = 0

x (x - 4) = 60

(x - 3) (x - 2) = 6 x - 18
