8 x^{2} + 6 x = 8

x = \frac{- 3 + 73}{8}, x = - \frac{3 + 73}{8}

Decimal Notation

x = 0.69300 \dots, x = - 1.44300 \dots

Solution steps

8 x^{2} + 6 x = 8

Move

8

to the left side

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

Solve with the quadratic formula

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

6^{2} - 4 \cdot 8 (- 8) = 273

x_{1, 2} = \frac{- 6 \pm 2 73}{2 \cdot 8}

Separate the solutions

x_{1} = \frac{- 6 + 2 73}{2 \cdot 8}, x_{2} = \frac{- 6 - 2 73}{2 \cdot 8}

x = \frac{- 6 + 2 73}{2 \cdot 8} : \frac{- 3 + 73}{8}

x = \frac{- 6 - 2 73}{2 \cdot 8} : - \frac{3 + 73}{8}

The solutions to the quadratic equation are:

x = \frac{- 3 + 73}{8}, x = - \frac{3 + 73}{8}

2 x^{2} - 1 = x^{2} + 8

- x^{2} + 6 x + 12 = 0

0.000015 (x + 100)^{2} = 0.2254

v^{2} - 3 v - 10 = 0

4 c^{2} = 25
