9 X^2 + 18 X + 9
=9 (X^2 + 2 X + 1)
=9 (X+1)(X+1)
or
(9X +9)(X+1)

divide the entire expression by 9
9(x2 +2x +1)
then factor what's in the ()
9 (x+1) (x+1)
that simplifies to:
9(x+1)2
nine times the quantity of x plus one, squared

Eyeballing this, one can see that 9 is a factor.
So, 9 (x^2 +2x +1)
Now we factor the polynomial into (x +1) (x+1)
And our final is 9 (x +1) (x+1)
You could also factor the 9 into 3 x 3
So, (3)(3)(x +1)(x+1)

9x^2 + 18x + 9
(3x + 3) (3x + 3)
the answer is a perfect square because both the first (9x^2) and last (9) terms are perfect squares.

(3x + 3) (3x + 3) is the answer.
or it can be (3x + 3)^2 ,
it doesn't matter, but that's the short version, they're both the same thing.
