x^{2} + 11 x + 18 = 0

x = - 2, x = - 9

Solution steps

x^{2} + 11 x + 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 \cdot 1 \cdot 18}{2 \cdot 1}

1 1^{2} - 4 \cdot 1 \cdot 18 = 7

x_{1, 2} = \frac{- 11 \pm 7}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 11 + 7}{2 \cdot 1}, x_{2} = \frac{- 11 - 7}{2 \cdot 1}

x = \frac{- 11 + 7}{2 \cdot 1} : - 2

x = \frac{- 11 - 7}{2 \cdot 1} : - 9

The solutions to the quadratic equation are:

x = - 2, x = - 9

b^{2} + 12 ab + 36 a^{2}

\frac{3}{4} + 3

3 x < 4 + x \leq 2 + 3 x

- 12.5 + \frac{1}{2} (- 9.8) (1.5)^{2}

4^{x} - 3 \cdot 2^{x} - 4 < 0
