Sketch the collection of algebra tiles that is described by the following expression. Rewrite the area of the collection by combining like terms.

Indicate how many , , and unit tiles are needed. Start by finding out how many total -tiles are needed.

Circle any term that has only one in it.
Then add the coefficients.

Note: A variable without a coefficient showing actually has a coefficient of .

Now do the same to find the number of tiles. How many unit tiles are needed?
