8 x^{2} - 6 x - 2 = 4

x = \frac{3 + 57}{8}, x = \frac{3 - 57}{8}

Decimal Notation

x = 1.31872 \dots, x = - 0.56872 \dots

Solution steps

8 x^{2} - 6 x - 2 = 4

Move

4

to the left side

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

Solve with the quadratic formula

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

(- 6)^{2} - 4 \cdot 8 (- 6) = 257

x_{1, 2} = \frac{- ( - 6 ) \pm 2 57}{2 \cdot 8}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 2 57}{2 \cdot 8}, x_{2} = \frac{- ( - 6 ) - 2 57}{2 \cdot 8}

x = \frac{- ( - 6 ) + 2 57}{2 \cdot 8} : \frac{3 + 57}{8}

x = \frac{- ( - 6 ) - 2 57}{2 \cdot 8} : \frac{3 - 57}{8}

The solutions to the quadratic equation are:

x = \frac{3 + 57}{8}, x = \frac{3 - 57}{8}

x^{2} - 2 x - 8

lo g_{\frac{1}{3}} (p) < 0

x + 1 = 7

x^{2} - 15 x - 100

- 6 v^{2} - 7 v - 2 = 0
