x^{2} + 9 x = - 18

x = - 3, x = - 6

Solution steps

x^{2} + 9 x = - 18

Move

18

to the left side

x^{2} + 9 x + 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 9 \pm 9 ^{2} - 4 \cdot 1 \cdot 18}{2 \cdot 1}

9^{2} - 4 \cdot 1 \cdot 18 = 3

x_{1, 2} = \frac{- 9 \pm 3}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 9 + 3}{2 \cdot 1}, x_{2} = \frac{- 9 - 3}{2 \cdot 1}

x = \frac{- 9 + 3}{2 \cdot 1} : - 3

x = \frac{- 9 - 3}{2 \cdot 1} : - 6

The solutions to the quadratic equation are:

x = - 3, x = - 6

x^{4} - 5 x^{3} + 4 x^{2} + 2 x - 8

\frac{5 + 4 i}{7 i}

2 x^{2} - 6 x + 5 = 0

3 x^{2} = 507

x^{2} + (\frac{3}{5})^{2} = 1
