im sorry but there is no z in the problem , i think you've mistaken 2 for z sorry about my penmanship :) lolMath_QED said:That's one way of solving it (observing that it is exact). I didn't check all steps though, so don't know if you are correct. You can fill in your solution in the differential equation and see if it works.
An alternative approach would be to divide both sides by ##x^2## and substitute ##z= y/x##

2(y^2+1)dx+(4xy-3y^2)dy=0
An exact differential problem is a type of differential equation where the dependent variable and its derivatives can be written as a total differential of a function. This means that the problem can be solved by finding the function and integrating it.
The general method for solving an exact differential problem involves identifying the dependent variable and its derivatives, checking for exactness by comparing the mixed partial derivatives, and then finding the integrating factor to solve for the function. Finally, the solution is obtained by integrating the function and adding a constant of integration.
The integrating factor for an exact differential problem can be found by dividing the coefficient of the differential term in the equation by the coefficient of the dependent variable. This factor is then used to multiply the entire equation, making it exact and allowing for the solution to be found.
Yes, an exact differential problem can have multiple solutions. This is because the constant of integration can take on different values, resulting in different functions that satisfy the equation. It is important to always include the constant of integration when solving an exact differential problem.
One tip for solving exact differential problems more efficiently is to always check for exactness before attempting to solve. This can save time and effort, as some problems may not be exact and require a different method of solving. Additionally, practicing with different types of exact differential problems can help improve problem-solving skills and speed.
