  1. no, try expanding your answer, you will not get the original.

    should be

    9D^3(2 + 5D^3)

  2. well it says:
    A 9D(2D+5D^5)
    B 6D^2(3+9D^4)
    C 3D^2(6+15D^4)
    D 9D^2(2+5D^4)

  3. And none of those answers , when expanded , will give you the original question the way you typed it.

    So what do you think????

    I also need you to check and make sure that I am using the FOIL method correctly for this problem. #82). 9w-w^3 9w-w^3=w*(w^2-9) I have to factor out the GCF, which is “w”. 9-w^2=3^2-w^2= (3-w) (3+w) = (3-w) (w+3) 3-w=-(w-3)
