Write for the equation.

One simple formula.

If you use the solutions of the equation Pell. Where

ask yourself.Make the change.

Then decisions can be recorded.

Use the ideas that basically involve formal and General approach.

But apparently the time has not come for them. Even attempt a discussion and a proposal to solve the equations in General form leads to the opposition.

http://mathoverflow.net/questions/23414 … -equations

Attempt to offer to solve an equation of the form

Only causes aggression and a desire to remove. With this notation explicitly perceived very well.

It is seen that the time for the ideas of formalization and a common approach is not yet.

Although attempts to reduce such ideas and methods you need to do.

The equation from there

http://math.stackexchange.com/questions … n-integers

For the equation.

You can write the solution in this form.

Such a record is better because allows to solve the symmetrical equation with any number of summands. It is only necessary to increase the number of parameters.

For the equation.

You can write for example the following parameterization.

We will use the solutions of Pell's equation.

Knowing the first solution i

For finding solutions in the case if the square is rational.

Use the same formula. For finding all solutions need to consider all possible solutions of the equation Pell. Consider the case where these solutions exist. To do this, lay on the multiplier coefficients.

And you need to check when this Pell equation has the solutions?

And then the solution is substituted in the above formula.

Consider the case which invited.

For the system of equations.

Solutions can be parameterized.

It is interesting that such triples can be too much. The formula can be increased to any number. That is the same to write not only for 4 partitions, but for any number. The main thing that all the variables were not identical to each other.

It turned out the following. For a square shape

If any number of options

and any coefficients . Solutions is always there.Illustrate 2 coefficients. Similarly solved if the number of different factors. That was evident symmetry and do not get confused is better to take 3 equation.

The solution is easy to write.

Here the representation of 3 options, but it is easy to see that can be written in the form of a combination with any number of options.

You can record a similar system.

Parametrization of solutions we write this.

Consider a special case.

Using the solutions of the equation Pell.

Enough to know first, everything else will find a formula.

The solution then write.

These solutions are negative.

And a positive decision of the same are determined by the Pell equation.

Use the first solution.

Next find the formula.

Will make a replacement.

The decision record.

For Diophantine equation

If the root is integer.

We use the solutions of the equation Pell.

The solution then can be written in this form.

To find all solutions is necessary to solve the more General equation. With different coefficients.

To solve this system of equations - it is necessary to solve the system.

It is necessary to find a parameterization to figurirovallo Pell. It is possible for example to record this.

We need a case of when.

Knowing the first decision

The rest can be found by the formula.

Although this equation can be not enough. We need to find when there are multiple solutions.
