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

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

Decimal Notation

x = 2.29099 \dots, x = - 0.29099 \dots

Solution steps

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

Solve with the quadratic formula

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

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

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

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

\frac{6 b}{2 ( b ) ^{3}}

- 5 v = \frac{10}{7}

\frac{π}{12} + \frac{π}{4}

5 x^{2} - 12 x + 4

x^{2} + 16 = 8 x
