square both sides
(x+4)^2 is the same as (x+4)(x+4)= x^2+8x+16
subtract both sides by 16
subtract both sides by x
Factor out an x
Now you have to find at what value of x the equation is equal to 0.
The obvious one is x=0
0*(0+7) is 0
The other one is x=(-7)
So x= -7, 0

x=0 is correct. Radical 16 = 4.
at x=-7, 3 radical 9 is not equal to -3
"3 radical 9" should have been posted as "radical 9"
There is no negative sign, explicit or inferred as far as I can see, in front of the radical sign in your problem statement. If you replace x with -7 in your problem equation and do the math, you will get on the left hand side,
On the right and side you will get -7+4=-3. 3 is unequal to -3. In other words -7 is not a solution to the problem as presented.
