Answer:Should be 144

Step-by-step explanation:If I remember correctly a perfect square trinomial is derived from a binomial squared. This one looks like it comes from (x + 12)^2, which when expanded would give you x^2 + 24x + 144.

(a+b)^2 = a^2 + 2ab + b^2

(a-b)^2 = a^2 -2ab + b^2

(a+b)(a-b) = a^2-b^2
