(3X + 9) (X + 9)
(x - 6)(x + 9)

Since both terms here are divisble by 3 then divide by 3 and factor our a 3...9/3x + 12/33(3x+4)
(-3x - 1)(3x - 7)
4x3+12x2+3x+9
(3X + 9) (X + 9)
3(x + 3)(x2 - 3x + 9)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
3x plus 9 equals what?
(8x + 9)(3x^2 - 1)
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
9x^2-6xy+y^2 = (y-3x)^2 (y-3x)^2-81 -> ((y-3x)+9)((y-3x)-9)
(x + 3)(x^2 - 3x + 9)
(x - 6)(x + 9)
