3 x^{2} - 6 x - 8 = 0

x = \frac{3 + 33}{3}, x = \frac{3 - 33}{3}

Decimal Notation

x = 2.91485 \dots, x = - 0.91485 \dots

Solution steps

3 x^{2} - 6 x - 8 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 3 ( - 8 )}{2 \cdot 3}

(- 6)^{2} - 4 \cdot 3 (- 8) = 233

x_{1, 2} = \frac{- ( - 6 ) \pm 2 33}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 2 33}{2 \cdot 3}, x_{2} = \frac{- ( - 6 ) - 2 33}{2 \cdot 3}

x = \frac{- ( - 6 ) + 2 33}{2 \cdot 3} : \frac{3 + 33}{3}

x = \frac{- ( - 6 ) - 2 33}{2 \cdot 3} : \frac{3 - 33}{3}

The solutions to the quadratic equation are:

x = \frac{3 + 33}{3}, x = \frac{3 - 33}{3}

x^{4} - 4 x^{2} + 4

\frac{3 + 4 i}{2 - 3 i}

12 \cdot 2

8 = 2 x - 9

\frac{5 x - 3}{x ^{2} - 25} \leq 0
