Is it possible to do this

432(140-x)^3 = 60480-432x^3

or do i have to expand it like this
432(140-x)(140-x)(140-x)

  • Math - ,

    The last way is correct.

  • Math - ,

    You will have to expand it, your first line is incorrect.

    test it with numbers...
    e.g.
    3(2^3) = 3(2)(2)(2) = 3(8) = 24
    the way you wanted to do it would be
    (6)^3 or 216
