Question

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

Answer 1

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?

Answer 2

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

Answer 3

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

Answer 4

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.
