x^{2} + 6 x - 9 = 0

x = 3 (2 - 1), x = - 3 (1 + 2)

Decimal Notation

x = 1.24264 \dots, x = - 7.24264 \dots

Solution steps

x^{2} + 6 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot ( - 9 )}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot (- 9) = 62

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

x = 3 (2 - 1), x = - 3 (1 + 2)

x^{2} - 7 x < 8

2^{x} = 3

9 x^{2} - 18 x + 8

\frac{x}{8} = \frac{8}{18}

40 - 2 (x + 5) = 3 (3 x + 1) - 17
