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

x = - \frac{- 7 + 301}{14}, x = \frac{7 + 301}{14}

Decimal Notation

x = - 0.73923 \dots, x = 1.73923 \dots

Solution steps

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

Move

6 x

to the left side

- 7 x^{2} + 7 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 ( - 7 ) \cdot 9}{2 ( - 7 )}

7^{2} - 4 (- 7) \cdot 9 = 301

x_{1, 2} = \frac{- 7 \pm 301}{2 ( - 7 )}

Separate the solutions

x_{1} = \frac{- 7 + 301}{2 ( - 7 )}, x_{2} = \frac{- 7 - 301}{2 ( - 7 )}

x = \frac{- 7 + 301}{2 ( - 7 )} : - \frac{- 7 + 301}{14}

x = \frac{- 7 - 301}{2 ( - 7 )} : \frac{7 + 301}{14}

The solutions to the quadratic equation are:

x = - \frac{- 7 + 301}{14}, x = \frac{7 + 301}{14}

x^{2} + 16 < 0

- 0.1 + 11 < 18 x + 31 - 11 + 11 < 0.1 + 11
