How do you expand linear expressions that involve multiplication addition and subtraction?

To expand linear expressions that involve multiplication, addition, and subtraction, apply the distributive property by multiplying each term inside the parentheses by the term outside. Then, combine like terms by adding or subtracting coefficients of similar variables. For example, in the expression (a(b + c) - d), distribute (a) to both (b) and (c) to get (ab + ac - d). Finally, make sure to simplify the expression if possible by combining any like terms.
