So for this, our equation can be rewritten as (thanks to distributive property): [tex] (6z^2*8)+(6z^2*(-3z))+(-4z*8)+(-4z*(-3z))+(1*8)+(1*(-3z)) [/tex]
Firstly, multiply everything: [tex] 48z^2-18z^3-32z+12z^2+8+-3z [/tex]
Next, combine like terms and your answer will be: [tex] -18z^3+60z^2-35z+8 [/tex]
