## Homework Statement

Find solution for y'' + y' -2y = 2x with initial values of y(0) = 0, y'(0) = 1

## Homework Equations

I have found yc = c1*exp(-2x) + c2*exp(x), but finding yp is what I'm having trouble with... AND THEN I'm not so sure how to go about the initial value.

## The Attempt at a Solution

Ok, so my "reasonable assumption" :

yp = Ax

y'p = A

y''p= 0

When I plug into equation, I get:

0 + A -2(Ax) = 2x... and that's where I'm stuck.

Any insights?
