EDITED: Here ya go Capitalist.

My answer was: x=5
The "Professor" says the answer is: x+3 yes that's plus...
========================================================
EDIT: Here's my post to the instructor. he hasn't responded yet.
9.5 Problem #8

(square root of (x+4))=3

My answer was x=5

(Square root of (5+4))=3
(Square root of (9))=3
3=3


Another way:

(Square root of(x+4))=3
((Square root of(x+4))=3) Squared
x+4=9
x=5

I just don't get why "5" is wrong. Am I crazy?

============================================================
So who is right?
