I think you need to check your final answer more carefully. BOTH x=9 AND x=4 are solutions. You need to consider the NEGATIVE square roots - think you'll find the square root of 4 is +2 AND -2.

Here is one 4 u. For every Math. teacher there are probably 20 English teachers.

Are these lessons free?

[foxrunmall]

yeah, that's true, 4 is also a solution as one of its square roots is -2. The guy in the video missed that point!

lol ur so right xD

@HarrysLimes I just assumed. I made an "ass" out of "u" and "me"

[HarrysLimes]

@falloutboy0403 I'm afraid that's simply not true. Try plotting the two graphs of y = x  and y = square root(x) +6 and tell me where the lines cross. You should find two solutions at x = 9 AND x = 4

One of the square roots of 4 is -2, and -2 + 6 = 4, so it IS a solution.

@HarrysLimes If you recheck your negative answers, you'll end up with an imaginary answer and an untrue statement.
