9 = - x^{2} - 6 x

x = - 3

Solution steps

9 = - x^{2} - 6 x

Switch sides

- x^{2} - 6 x = 9

Move

9

to the left side

- x^{2} - 6 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 ( - 1 ) ( - 9 )}{2 ( - 1 )}

(- 6)^{2} - 4 (- 1) (- 9) = 0

x_{1, 2} = \frac{- ( - 6 ) \pm 0}{2 ( - 1 )}

x = \frac{- ( - 6 )}{2 ( - 1 )}

\frac{- ( - 6 )}{2 ( - 1 )} = - 3

x = - 3

The solution to the quadratic equation is:

x = - 3

x^{3} - 12 x^{2} + 48 x - 64

8 x^{3} + 27 g^{3}

0 = - x^{2} + 9

2 x - 3 = 9

- 4175 - 112
