how would I find each sum or difference of
(5a-2b) + (-4a+5b)

what do I do with -2b when you line up the +5b?

  • math - ,


  • math - ,

    The sum of the two terms in parentheses is a - 3b

    If you want the difference, it should be written
    (5a - 2b) - (-4a + 5b)
    which is the same as
    (5a - 2b) + (4a - 5b) = 9a - 7b
