5y''+y'=-6x

OpenStudy (anonymous):

sorry its a undetermined coefficient problem

zepdrix (zepdrix):

Were you able to find the complimentary solution ok? :)

OpenStudy (anonymous):

subtract y on both sides first and divide by the number thats in front of the variable

OpenStudy (anonymous):

yes

zepdrix (zepdrix):

\[5r^2+r=0\]\[r(5r+1)=0\]\[r=0,r=-1/5\]\[\large y_c=c_1e^0+c_2e^{\frac{ -1 }{ 5 }x}=c_1+c_2e^{\frac{ -1 }{ 5 }x}\] Ok lemme make sure we're on the same page :D is that what you came up with for the complimentary part?

OpenStudy (anonymous):

yes thats what I got, and is the Yp=6x?

|dw:1351369202691:dw| Ok here is how we want to approach the particular solution, let me know if it's confusing :O
