Question 170720: Hi,
I am having doubts that I solved this problem correctly. Here is my work.
(square root of x + 2) - 2 = (square root of x + 9)
i squared both sides.
x + 9 = x + 2 - (14square root of x + 2) + 49
9 = 51 -(14square root of x + 2)
-42= square root of x + 2
1764 = x + 2
x = 1762
when I substitute 1762 into the original equation and found it to be extraneous. Is this correct?

Question 170820: Hi again. I found another problem that is confusing.
square root of 2x = the square root of x/4
i tried to break the square root of x/4 into (sqr x/ sqr 4). then i squared both sides
= 2x = x / 4
then i multiplied both sides by 1/x.
=2x/x = 1/4
2x/x = x
so x = 1/4
Is this the correct way to approach this problem?
Thank you.
