Simplify: Can someone please help me with this and go through the steps for it please. Thank You

-8z(-9z^2-z-1)

  • prealgebra -

    Start with the distributive law:
    A(B+C)
    =AB+AC
    and similarly
    A(B+C+D)
    =AB+AC+AD

    Try:
    4x(5x2+3x+2)
    =4x*5x2 + 4x*3x + 4x*2
    =20x3 + 12x2 + 8x

    Can you try your problem now?

  • prealgebra -

    i still don't understand on how to do the problem

  • prealgebra -

    would the answer for the problem that i sent you be 72z^3-8z^2-1

  • prealgebra -

    You have to multiply -8z by all terms. Also remember that a negative times a negative equals a positive.

    72z^3 + 8z^2 + 8z

    I hope this helps a little more. Thanks for asking.
