Christine Mccall · Answer 2

This is the concept of algebra, from the above question the product that was found using the algebra tiles was:

3x * (2x-1)

=3x (2x-1)

From above we can conclude that he used the products correctly. Even though he never expanded the final expression, the answer still holds.

Therefore the correct answer is A]
