As I'm not even sure what type of problem this is, so I can't research it.
Could I get an explanation (with example) of how to solve the above equation? Or direct me to a resource with the explanation (preferably Khan Academy)? I am not looking for the answer to this problem, just the way I would solve it.
What I've attempted:
- I have tried making it a perfect square, but can't get past the odd numbers.
- I have tried squaring everything, and using the quadratic formula, but it doesn't match the answer format.
Any help is greatly appreciated!
