- 7 x^{2} + 4 x + 6 = 0

x = - \frac{- 2 + 46}{7}, x = \frac{2 + 46}{7}

Decimal Notation

x = - 0.68318 \dots, x = 1.25461 \dots

Solution steps

- 7 x^{2} + 4 x + 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 ( - 7 ) \cdot 6}{2 ( - 7 )}

4^{2} - 4 (- 7) \cdot 6 = 246

x_{1, 2} = \frac{- 4 \pm 2 46}{2 ( - 7 )}

Separate the solutions

x_{1} = \frac{- 4 + 2 46}{2 ( - 7 )}, x_{2} = \frac{- 4 - 2 46}{2 ( - 7 )}

x = \frac{- 4 + 2 46}{2 ( - 7 )} : - \frac{- 2 + 46}{7}

x = \frac{- 4 - 2 46}{2 ( - 7 )} : \frac{2 + 46}{7}

The solutions to the quadratic equation are:

x = - \frac{- 2 + 46}{7}, x = \frac{2 + 46}{7}

z^{2} - 7 z - 8 = 0

464 x^{2} - 368 x + 5376 = 0

5 x^{2} - 2 x + 7 = 0

4 x^{2} + 4 x - 3 = 0

2 x + 8 x^{2} = 4 x + 5
