All of these questions you ask for help are about the same thing. Simply sqaure what's inside the square root (get rid of the radical or square root sign) and then solve the equation by using subtract, addition, and/or division.

But you can't do nothing to the x

In all these questions, isolate the radical part on one side and the rest of the terms on the other side. Then square on both sides to get rid of the radical.

jhonyy9 · Answer

2 +sqrt(x+4) = x subtract from both sides 2

sqrt(x+4) = x-2   squared both sides 

x+4 = (x-2)^2

x+4=x^2 -4x +4

do you can continue it now ?

To solve this type of problem, you want to get rid of the radical fist. To do so, you will want to get the radical on one side of the equation by itself. 

One way to do this is to subtract 2 from both sides, which will give you 

2 + sqr(x + 4) = x
-2                         - 2
sqr(x + 4) = x - 2

Once you have a radical by itself, you can square both sides of the equation to get rid of the radical. This will look like this:

[sqr(x + 4)]^2 = (x - 2)^2

x + 4 = (x - 2) ^2
x + 4 = x^2 - 4x + 4

Now you can collect like terms and solve the quadratic for x. 

I hope this helps.
