It often helps to square both sides of the equation (or raise to some other power, such as to the power 3, if it's a cubic root).Please note that doing this may introduce additional solutions, which are not part of the original equation. When you square an equation (or raise it to some other power), you need to check whether any solutions you eventually get are also solutions of the original equation.
It often helps to isolate the radical, and then square both sides. Beware of extraneous solutions - the new equation may have solutions that are not part of the solutions of the original equation, so you definitely need to check any purported solutions with the original equation.
To solve for this, you need to isolate "m." To accomplish this, subtract 4m from both sides of the equation. This should change the equation to q - 4z = 4m. Then you divide both sides by 4, getting q/4 - 4z/4 = m. After completing the division, you should get 1/4q - z = m.
Example: 2x/7 = 12 First, multiply the reciprocal of 2/7, which is 7/2, to both sides of the equation to isolate x. You should now have: x = 12 x 7/2 --> x= 6 x 7 --> x = 42 *simplify 12 x 7/2 by cancelling two from 12 and 2. I'm not sure if this is what you're asking for, but hopefully it helps.
Practice - and problem solving ! If you explain clearly how the problem should be solved - and give them enough examples - they should absorb the teachings, and apply them to a new problem !
The rules for "standard radical form" are that (a) there should be no perfect square within the radical sign; for example, square root of 12 is equal to square root of 4 x square root of 3 = 2 x square root of 3, and should be written as the latter; and (b) there should be no radical sign in the denominator. For example, if you have 1 / square root of 2, you multiply top and bottom by the square root of 2, to get a square root in the numerator, but none in the denominator.
Radical...Apex :)

That depends on the equation; you need to give some examples of what you want factored. There are four steps to solving an equation. Should any other factors be accounted for when solving an equation? Should any factors be accounted for when explaining how to solve an equation?

If you are solving for y, it is fine. If you are solving for x, divide both sides by x and the equation should be x = y/x

A "radical" equation is an equation in which at least one variable expression is stuck inside a radical, usually a square root. The "radical" in "radical equations" can be any root, whether a square root, a cube root, or some other root. Most of the examples in what follows use square roots as the radical, but (warning!) you should not be surprised to see an occasional cube root or fourth root in your homework or on a test.
Yes. Since "these" do not exist, cjanging them should not make a difference.
Different equations call for different steps to be followed when solving them. Exponents, parenthesis, addition, subtraction, multiplication and division are all generally used.
By solving the simultaneous equations the values of x and y should be equal to the given coordinate
The following two details should be quite easy to remember. 1) "Do the same on both sides." (Whatever you do on one side of the equation, you must do the same on the other side.) 2) "Isolate the variable." Though you can do just about any operation, you should do operations in such a way that the variable which you are solving for will be alone on one side; anything else, on the other side. All else is practice, and learning some special cases.
John should have first found the lowest common denominator of the given fractions.
