9 x^{2} - 12 x - 12 = 0

x = 2, x = - \frac{2}{3}

Decimal Notation

x = 2, x = - 0.66666 \dots

Solution steps

9 x^{2} - 12 x - 12 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 9 ( - 12 )}{2 \cdot 9}

(- 12)^{2} - 4 \cdot 9 (- 12) = 24

x_{1, 2} = \frac{- ( - 12 ) \pm 24}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 12 ) + 24}{2 \cdot 9}, x_{2} = \frac{- ( - 12 ) - 24}{2 \cdot 9}

x = \frac{- ( - 12 ) + 24}{2 \cdot 9} : 2

x = \frac{- ( - 12 ) - 24}{2 \cdot 9} : - \frac{2}{3}

The solutions to the quadratic equation are:

x = 2, x = - \frac{2}{3}

x, x (x - 4) = 140

x^{2} = 10 x - 50

x^{2} - 14 x + 20 = - 4

6 y^{2} - 7 y + 2 = 0

x - (x - 7)^{2} = 1 + x - 6 x^{2}
