Expanding Expressions with Integers

When a number or variable is up next to another variable or a parenthesis without a space, that means you need to multiply.

-4 is how many groups you need of everything in parenthesis.

Terms to multiply by -4= 4a and -3

Distributive Property is when you multiply everything on the outside of the parenthesis by everything on the inside of the paranthesis.

Distribute (multiply) the -4 to the 4a and the -3. $4\left(4a\right)\ +\ 4\left(-3\right)$  

Final Answer:  $16a\ -\ 12$
