x^2 - 6x + 36 can be factored as (x-6)^2
x^2 - 10x + 25 can be factored as (x-5)(x-5) or (x-5)^2
4x^2 - 49 can be factored as (2x+7)(2x-7) or (2x+7)(2x+7)
4x^2 + 12x + 9 can be factored as (2x + 3)(2x + 3) or (2x + 3)^2
Therefore, the factorable expressions are:
x^2-6x+36
x^2-10x+25
4x^2 - 49
4x^2 + 12x + 9
