\frac{1}{3} x^{2} - x - 18 = 0

x = 9, x = - 6

Solution steps

\frac{1}{3} x^{2} - x - 18 = 0

Multiply both sides by

3

x^{2} - 3 x - 54 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 1 \cdot ( - 54 )}{2 \cdot 1}

(- 3)^{2} - 4 \cdot 1 \cdot (- 54) = 15

x_{1, 2} = \frac{- ( - 3 ) \pm 15}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 3 ) + 15}{2 \cdot 1}, x_{2} = \frac{- ( - 3 ) - 15}{2 \cdot 1}

x = \frac{- ( - 3 ) + 15}{2 \cdot 1} : 9

x = \frac{- ( - 3 ) - 15}{2 \cdot 1} : - 6

The solutions to the quadratic equation are:

x = 9, x = - 6

x (x + 7) = - 12

x^{2} + 17 x + 77 = 0

14 x^{2} - 11 x = 3

8 z^{2} + 2 z - 1 = 0

(2 + 2 x) (4 + 2 x) = 72
