x^{2} + 6 x - 1 = - 7

x = - 3 + 3, x = - 3 - 3

Decimal Notation

x = - 1.26794 \dots, x = - 4.73205 \dots

Solution steps

x^{2} + 6 x - 1 = - 7

Move

7

to the left side

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

Solve with the quadratic formula

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

6^{2} - 4 \cdot 1 \cdot 6 = 23

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

Separate the solutions

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

x = \frac{- 6 + 2 3}{2 \cdot 1} : - 3 + 3

x = \frac{- 6 - 2 3}{2 \cdot 1} : - 3 - 3

The solutions to the quadratic equation are:

x = - 3 + 3, x = - 3 - 3

3 x - 5 < - 17 and - 6 x + 5 > 11
