Hi, I am solving a system of differential equations and in one of my equations I have this,
(D+2)X+(D+2)Y=0 where X and Y are variables, D is my differential operator.
My question is, would it be mathematically correct to divide out (D+2)
and thus getting X+Y=0, X=-Y ?

A differential operator is a mathematical operator that acts on a function to produce another function. It is used to describe the relationship between a function and its derivatives.
The properties of differential operators include linearity, commutativity, and associativity. They also follow the product rule, quotient rule, and chain rule.
Differential operators act on functions by taking the derivative of the function with respect to the variable it is operating on. For example, the operator d/dx acts on a function f(x) to produce f'(x).
The order of a differential operator is the highest derivative present in the operator. For example, the operator d^3/dx^3 is of third order.
A partial derivative is a derivative of a multivariable function with respect to one of its variables, while a total derivative takes into account the dependence of the function on all of its variables. In other words, a partial derivative holds all variables except the one it is differentiating with respect to constant, while a total derivative takes into account the changes in all variables.
