Using algebra tiles is a visual way to solve the problem of the polynomials, for you can get the answer using simple rules and finding it not hard to solve.

 

So let’s look at the legend of the Algebra Tiles:

Here’s an example of using algebra tiles to expand 2 binomials.

So what you need to do is to fill in the blank bottom right of the cross by using the multiply rules.

The result is the tiles in the bottom right is the result of the polynomial. Sometimes it needs to be simplified, like in here, there’s 2 positive sticks and 1 negative stick, so the simplification would be 1 positive stick.

So the result would be

 

And here’s how you rewind a polynomial into a 2 binomial multiple:

So this represents 

Try to put the tiles into a position that make sense to the rules in algebra tiles and fill in the blanks with equal numbers of positive/negative tiles:

Then put the set into the cross and we get the result:
