I know i'm a slow bunny and the answer is in my face but please help!
(4p-1)(16p^2+4p+1)

  • math -

    Multiply (16p^2+4p+1) by 4p, and then subtract (16p^2+4p+1) from what you get.
    64p^3 + 16 p^2 + 4p - 16p^2 -4p -1
    = 64 p^3 -1.

    sorry man I still don get it. I have to find the product. I don't know where you got the 64^3 from. Can you please take me step by step

  • math -

    There was no 64^3 in my anser.

    64p^3 is the product of the 16 p^2 and 4p terms. I suggest you review the distributive propery of algebra:
    a (b +c) = ab + ac

    ok thanks
