x^{2} + 9 x + 20 = 0

x = - 4, x = - 5

Solution steps

x^{2} + 9 x + 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 1 \cdot 20}{2 \cdot 1}

9^{2} - 4 \cdot 1 \cdot 20 = 1

x_{1, 2} = \frac{- 9 \pm 1}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 9 + 1}{2 \cdot 1}, x_{2} = \frac{- 9 - 1}{2 \cdot 1}

x = \frac{- 9 + 1}{2 \cdot 1} : - 4

x = \frac{- 9 - 1}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = - 4, x = - 5

4 x^{2} + 8 x + 8 = 0

3 (\frac{1}{3})^{3} - 10 (\frac{1}{3})^{2} - 27 (\frac{1}{3}) + 10

(\frac{1}{125 x ^{3}})^{- \frac{1}{3}}

x + 5 \geq 3

2 > \frac{x}{3} - 1
