If x²=144, then x = positive 12 and x = negative 12.
I have no idea what the '72' is doing in there.
If it means x²=144.72, then
x = + / - 12.03 (rounded)
Oh wait. Now I understand what the 72 is. It's one of the answer choices.
Specifically, it's the customary absurd choice for students who have no clue.
