Math Problem Statement

Is the following differential equation homogeneous or non-homogeneous?

y'' + 3y' - 2 = 5x + 1

Your written work for this problem is just a quick explanation.

Solution

To determine if the differential equation is homogeneous or non-homogeneous, we examine whether there is a non-zero term on the right-hand side of the equation.

The given equation is: y+3y2=5x+1y'' + 3y' - 2 = 5x + 1

For a differential equation to be homogeneous, the equation must equal zero, meaning the entire right side should be zero. Here, the right side is 5x+15x + 1, which is not zero. Therefore, this equation is non-homogeneous.

In summary:

  • Since the equation does not equal zero but rather 5x+15x + 1, it is a non-homogeneous differential equation.
