NaCl(s) is table salt in solid form.

NaCl(aq) is table salt in aqueous solution (salt water for example)

H2O(s) is solid water, otherwise known as ice

H20(g) is gaseous water, otherwise known as water vapor

H2O has no free electrons and in pure form does not conduct electricity in solid or gaseous state.

In solid state, the NaCl molecules are tightly interconnected in a crystalline structure with no free electrons.   Solid table salt also doesn't conduct electricity.

However, table salt can dissolve in water (or in some other aqueous solution) to form Na+ and CL- ions and form a great electrical conductor.

First you have to distribute the 6x to the 4x+4 to get.

24x^2+24x=38

Since there are no easy factors, we'll need to proceed with the completing square method.

First divide both sides by 24

x^2+x=38/24

Then complete the square on left

(x+1/2)^2 - 1/4 = 38/24

(x+1/2)^2 = 44/24

x+1/2 = +- 44/24

x = -1/2 +- 11/6

35,786 km (22,236 mi) above sea level for a satellite in geosynchronous orbit over the equator.

This is actually a special case but it's the most frequently cited number.

First thing you have to do is 

(x-3)^2 = x^2-6x+9

x^2-6x+2 = (x^2-6x+9) - 7= (x-3)^2 - 7 = 0

(x-3)^2 =  7

x-3 = sqrt(7)

x = 3 +- sqrt (7)

Perfect answer

 Not if it were x<=-11, the answer would be (-infinity, -11] with the bracket indicating including -11.
