Here is how we get the equation that best represents the general form of the given expression above.
Since we have a fraction, what we are going to do in order to eliminate it is to multiply both sides by 2. So this gives us x^2 = 14x.
Move 14x, and the final form would be x^2 -14x = 0.
Hope this is the answer that you are looking for.
