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

x = - \frac{- 3 + 15}{3}, x = \frac{3 + 15}{3}

Solution steps

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

Solve with the quadratic formula

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

6^{2} - 4 (- 3) \cdot 2 = 215

x_{1, 2} = \frac{- 6 \pm 2 15}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- 6 + 2 15}{2 ( - 3 )}, x_{2} = \frac{- 6 - 2 15}{2 ( - 3 )}

x = \frac{- 6 + 2 15}{2 ( - 3 )} : - \frac{- 3 + 15}{3}

x = \frac{- 6 - 2 15}{2 ( - 3 )} : \frac{3 + 15}{3}

The solutions to the quadratic equation are:

x = - \frac{- 3 + 15}{3}, x = \frac{3 + 15}{3}

x^{2} - 8 x - 9

g^{2} - 10 g = - 19

2 (4 x - 3) - 8 = 4 + 2 x

y^{2} - 8 y + 12 = 0

- x \leq 5
