Another awesome Distributive Property mistake

distributive property

We actually have an explanation from the student, and hopefully Alison Royster will be kind enough to jump in on the comments and provide it.

Sorry to be so late responding! Somehow I missed this post. You’re all correct — I asked this student about his work, and he said that he multiplied the like terms. What’s especially frustrating is that this was a review problem, within a week or two of extensive work on the distributive property, including using the area model of the distributive property (and linking those to the symbolic representation), and I really thought this student understood the distributive property!
