Question

NonHomegeneous Equation. Using the Method of Undetermined Coeff.
y"(x)+y'(x)=2^x

Answer 1

Have you solve y''+y'=0?

Answer 2

no I have not

Answer 3

so r= -1 and r= 0

Answer 4

I am unsure of the equation I am supposed to use since this is equal to a power function

Answer 5

I am assuming we will use the natural log at some point but I do not what to do to get there

Answer 6

Ok so we already know part of the solution looks like y=ae^{-t}+b
Now for the part that involves the homogeneous part
try y=c2^x

Answer 7

sorry for never responding. we ended up going over this in class and I forget to close the question
