simplify

2a^2 + 6ab^2-12a^2b^3 divided by 24ab
-2a^2/-24ab + 6ab^2/24ab--12a^2b^3/24ab=
-12ab^2 +12a +4b

  • algebra - ,

    -2a^2 / 24ab is not -12ab

    It is -a/12b
    because you have -(2a)(a) / (2a)(12b)
    and the 2a's cancel

    6ab^2/24ab = (6ab)(b) / (6ab)(4) = b/4

    12a^2b^3 / 24ab = (12ab)(ab^2) / (12ab)(2) = ab^2/2
