Which of the quadratic expressions is factorable over the integers? select all that apply. 16x^2 -36
x^2 -6x +36
x^2 -4x +4
36x^2 +108x +81
25x^2 +30x +36

16x^2 -36 does factorise

x^2 -6x +36 don't factorise

x^2 -4x +4 does factorise as (x−2)(x−2)

36x^2 +108x +819 does factorise as (2x+3)(2x+3)

25x^2 +30x +36 don't factorise

Hope this helps!
