QUESTIONS:
The first time I tried this problem I found it challenging because it took a while to expand and square all the components. I doubted myself a few times cause of the high numbers but trusted the process and saw it through.
The mistake I made when I first did this problem was I did not fully factor the squared binomials, so I had to go back and redo them.
Some strategies I used to help me solve this problem: I looked at similar problems to see the steps involved to solve them and applied them to this problem.
Some concepts and skills I needed to remember in order to solve this problem were squaring binomials, adding, subtracting, and squaring both sides of the equals sign at the same time.
Next time I encounter a difficult problem, I might try to find the restrictions for x first, then put everything I can onto one side of the equals sign, and square all the terms to get rid of the radicals. Then I will double check my answers as I go to make sure they make sense.
