@crunchy man, if you use a grid to expand the brackets (multiply out the numbers you have), you get 2a^2 +2b^2 +2ab +2ab as (2a x 2a) = 2a^2 (same with 2b) then: (2a x 2b) gives 2ab and visa versa. You then add the two separate ab numbers giving you your final answer of 2a^2 2b^2 4ab

This student sets low personal standards, and then consistently fails to achieve them.
