    (6x+7) (6x-7)

    Step-by-step explanation:

    Why this is, is because of the positive and negative sign in the expression.

    With a positive and a negative it will cancel something.

    36x^2-42x+42x-49. The - 42x and the + 42x cancel out because the are added together to get 0 so your answer is.

    (6x+7) (6x-7).
