x (x + 6) = - 9

x = - 3

Solution steps

x (x + 6) = - 9

Expand

x (x + 6) : x^{2} + 6 x

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 \cdot 1 \cdot 9}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot 9 = 0

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

x = \frac{- 6}{2 \cdot 1}

\frac{- 6}{2 \cdot 1} = - 3

x = - 3

The solution to the quadratic equation is:

x = - 3

lo g_{6} (x) < - 3

\frac{3}{4} x - 3 + 1 \leq 15

v^{2} - 8 v + 16 = 0

(a - 3)^{2} = 6

\frac{3}{4} x^{2} + 1 = 31
