The first time that I tried this problem I found it challenging because I did not know what should I do with the bracket.

The first time that I tried it, I squared everything inside of the brackets.

The strategies that I used to figure it out were: 1- I asked for help from my teacher. 2- I listened carefully to all my teacher’s explanations and tried to learn the solution. 3- I watched YouTube videos about this kind of problem, and I did some problems like this problem, in order to remember everything completely.

The skill that I used to solve this problem correctly was: foiling the squared binomial and combining like terms to solve the rest of the problem.

Next time I encounter a difficult problem, I might use the same strategies to figure out future problems.
