Answer:
Step-by-step explanation:
This product can be solved by multiplying these parentheses left to right using a distributive property.
Distributive property:
[tex]\Longrightarrow:\sf{A(B+C)=AB+AC}[/tex]
[tex]\Longrightarrow: \sf{-n(6n+3)=-n*6n-n*3}[/tex]
Rewrite the problem down.
-n*6n-n*3
Solve.
-n*6n-n*3=-6n²-3n
[tex]\Longrightarrow:\boxed{\sf{-6n^2-3n}}[/tex]
