    You're asking if:

    (4x + 1)^2 = 16x^2 + 1, when x = 2

    (4(2) + 1)^2 = 16(2)^2 + 1

    (9)^2 = 64 + 1

    81 = 65; no.

    I'm confused what you're trying to ask for hte second part. You're asking if the "answers match" if you use x = 2, but you have p as your variable.

    Further, you have an expression.

    Perhaps you could clarify what you're asking for.
