To complete the square for the expression (3x^2 - 12x + 9), first factor out the 3 from the first two terms: (3(x^2 - 4x) + 9). Next, to complete the square inside the parentheses, take half of (-4) (which is (-2)), square it (getting (4)), and then adjust the expression: (3(x^2 - 4x + 4 - 4) + 9). This simplifies to (3((x - 2)^2 - 4) + 9), resulting in (3(x - 2)^2 - 12 + 9), or finally (3(x - 2)^2 - 3).

What is the factorization of the trinomial 3x2 plus 36x plus 81?
3x2 + 36x + 81 = 3(x2 + 12x + 27) = 3(x + 3)(x + 9), which are its prime factors; or, if you prefer, 3x2 + 36x + 81 = (3x + 9)(x + 9), which is also accurate. You may easily verify these results by multiplying back.
