Find the general solution of the given differential equation.
y' = 2y + x² + 3
Give the largest interval over which the general solution is defined.
Determine whether there are any transient terms in the general solution.
Step 1
Recall that the standard form of a linear first-order differential equation is as follows.
dy
dx
We are given the following equation.
y' = 2y + x² + 3
This can be written in standard form by subtracting the term in y from both sides of the equation.
dy - 2y = x² + 3
dx
+ P(x)y = f(x)
Thus, we have the following coefficient functions from the standard form.
