 2                                
a  + 6*a + 9 + (a + 3)*(3 - a) = 0
$$a^{2} + \left(- a + 3\right) \left(a + 3\right) + 6 a + 9 = 0$$
Detail solution
Given the equation:
a^2+6*a+9+(a+3)*(3-a) = 0

Expand expressions:
a^2 + 6*a + 9 + 9 - a^2 = 0

Reducing, you get:
18 + 6*a = 0

Move free summands (without a)
from left part to right part, we given:
$$6 a = -18$$
Divide both parts of the equation by 6
a = -18 / (6)

We get the answer: a = -3
