    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
