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

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

Decimal Notation

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

Solution steps

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

Write in the standard form

a x^{2} + b x + c = 0

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{1}{3}

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

The solutions to the quadratic equation are:

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

(3 x + 5)^{2} = 0

6 x^{2} + 3 = - 11 x

5 y (2 y - 5) = 0

x^{1} + 2 x^{2} = 8, 3 x^{1} - 4 x^{2} = 4

10 t^{2} - 4 t - 32 = 0
