factor it. 81r^236rs+4s^2

you try, see above example that I did for you.
you won't learn how to factor without trying
post back where you are stuck 
i have no idea how to do this...

81r^2  36rs + 4s^2
this one is a little harder than the above one I did for you
(9r  2s)(9r  2s) = (9r  2s)^2
this is factored form.
