Distributing VariablesA variable can be distributed into a set of parentheses just as we distributed a negative sign or a number. Consider the following example. x(y + 1) We can now apply the distributive property to the expression by multiplying each term inside the parentheses by x. x * y + x * 1 Now simplifying the multiplication, we get a final answer of xy + x The same is true when a problem consists of a number, variables, and parentheses: 4x(x^{2} + 9) Again, multiply each term inside the parentheses by the multiplier outside the parentheses. 4x * x^{2} + 4x * 9 Then simplify 4x^{3} + 36x The next page has several resources including worksheets and related calculators.
