- 12 x^{2} + 5 x + 2 = 0

x = - \frac{1}{4}, x = \frac{2}{3}

Decimal Notation

x = - 0.25, x = 0.66666 \dots

Solution steps

- 12 x^{2} + 5 x + 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 ( - 12 ) \cdot 2}{2 ( - 12 )}

5^{2} - 4 (- 12) \cdot 2 = 11

x_{1, 2} = \frac{- 5 \pm 11}{2 ( - 12 )}

Separate the solutions

x_{1} = \frac{- 5 + 11}{2 ( - 12 )}, x_{2} = \frac{- 5 - 11}{2 ( - 12 )}

x = \frac{- 5 + 11}{2 ( - 12 )} : - \frac{1}{4}

x = \frac{- 5 - 11}{2 ( - 12 )} : \frac{2}{3}

The solutions to the quadratic equation are:

x = - \frac{1}{4}, x = \frac{2}{3}

- 8 x^{2} + 3 x - 7 = 0

2 x^{2} - 6 = 4 x

- 12 x + 7 = 5 - 2 x^{2}

s^{2} = 0

r^{2} + 4 r + 8 = 0
