Question

Short answer please Find the following product: -3z(z^3 - 3z^2 + 6)

Answer 1

-3z^4+9z^3-18z

Answer 2

how did you get it though

Answer 3

Multiply -3z with each term inside the bracket.

Answer 4

okay -3z needs to times all the parts inside the brackets

-3z*z^3-3z*-3z^2-3z*6
= -3z^(1+3)+9z^(1+2)-18z
= -3z^4+9z^3-18z

Answer 5

-3z(z^3 - 3z^2 + 6)
=-3z^4+9z^3-18z

Answer 6

yes correct.
