9 x^{2} - 9 x - 4 = 0

x = \frac{4}{3}, x = - \frac{1}{3}

Decimal Notation

x = 1.33333 \dots, x = - 0.33333 \dots

Solution steps

9 x^{2} - 9 x - 4 = 0

Solve with the quadratic formula

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

(- 9)^{2} - 4 \cdot 9 (- 4) = 15

x_{1, 2} = \frac{- ( - 9 ) \pm 15}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 15}{2 \cdot 9}, x_{2} = \frac{- ( - 9 ) - 15}{2 \cdot 9}

x = \frac{- ( - 9 ) + 15}{2 \cdot 9} : \frac{4}{3}

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

The solutions to the quadratic equation are:

x = \frac{4}{3}, x = - \frac{1}{3}

3 x^{2} + 12 x - 36 = 0

λ^{2} - 4 λ - 5 = 0

x^{2} - 22 x + 112 = 0

x^{2} + 6 x = - 18

3 x^{2} + 9 x + 5 = 0
