3 x^{2} - 6 x - 9 = 0

x = 3, x = - 1

Solution steps

3 x^{2} - 6 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 3 ( - 9 )}{2 \cdot 3}

(- 6)^{2} - 4 \cdot 3 (- 9) = 12

x_{1, 2} = \frac{- ( - 6 ) \pm 12}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 12}{2 \cdot 3}, x_{2} = \frac{- ( - 6 ) - 12}{2 \cdot 3}

x = \frac{- ( - 6 ) + 12}{2 \cdot 3} : 3

x = \frac{- ( - 6 ) - 12}{2 \cdot 3} : - 1

The solutions to the quadratic equation are:

x = 3, x = - 1
