IV. Solve
y''' - y'' - y' + y - x = 0
So then I moved the equation to r^3-r^2-r+y-x
So an obvious answer would be like r=1
So I need to somehow divide by r-1 in order to get a quadratic or something.
Then I need to find some specific solution maybe using y(x)= Ax+ B for some numbers A and B.
But I need help executing that.
