can someone help me simplify 2a^2b^3(4a^2+3ab^2-ab)=? the first part of the answer is 8a^4

  • algebra1 -

    not quite, you forgot the b part

    1st term ---- 8a^4 b^3
    etc.

  • algebra1 -

    2a^2b^3(4a^2+3ab^2-ab)
    = 2a^2b^3*4a^2
    + 2a^2b^3*3ab^2
    - 2a^2b^3*ab

    = 8a^4b^3 + 6a^3b^5 - 2a^3b^4
