x^{2} + 18 x = 6

x = - 9 + 87, x = - 9 - 87

Decimal Notation

x = 0.32737 \dots, x = - 18.32737 \dots

Solution steps

x^{2} + 18 x = 6

Move

6

to the left side

x^{2} + 18 x - 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 18 \pm 1 8 ^{2} - 4 \cdot 1 \cdot ( - 6 )}{2 \cdot 1}

1 8^{2} - 4 \cdot 1 \cdot (- 6) = 287

x_{1, 2} = \frac{- 18 \pm 2 87}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 18 + 2 87}{2 \cdot 1}, x_{2} = \frac{- 18 - 2 87}{2 \cdot 1}

x = \frac{- 18 + 2 87}{2 \cdot 1} : - 9 + 87

x = \frac{- 18 - 2 87}{2 \cdot 1} : - 9 - 87

The solutions to the quadratic equation are:

x = - 9 + 87, x = - 9 - 87

(\frac{3 x ^{7} y ^{9}}{5 x ^{5} y ^{2}})^{- 4}

x^{2} + 6 x + 5 \leq 0
