Question 180022: a recent homework example said fine the domain of the function:

g(x) = x/ (over) x^2 + 9x +14
Want us to find any values of x that are meaningless, specifically, that would make the denominator = 0. to do this make the denominator = 0
So, x^2 +9x+14 = 0
to show the way to solve it, they now show (x+2)(x+7)=0
Therefore, X= -2, -7
How do you get (x+2)(x+7) = 0 from x^2+9x+14+0?????? What happened here? And where did the '9x' go ??? I am totally confused in how they worked out that -2 and -7 are meaningless. how did they get to this?
