[00:00:26] hi. where should we begin?

Guest (Customer) (Customer)
[00:00:45] hi, at the beginning

ELIZABETH C (Tutor)
[00:01:17] good answer. do you know what this kind of problem is called?

Guest (Customer) (Customer)
[00:01:52] no, but I should

ELIZABETH C (Tutor)
[00:02:59] that's ok. x^2 is a perfect square because we can take the square root. 121 is also a perfect square. also, we are subtracting... so we call it the difference of squares
[00:03:44] may i show you an example and let you then do this one?

Guest (Customer) (Customer)
[00:04:15] yes

ELIZABETH C (Tutor)
[00:06:52] just take both square roots. make the first factor + and the second one -. that is the answer
