Factor is not the correct word for what I believe you are supposed to do.
You are combining terms. Use the distributive property to combine the constants associated with a variable as follows:
Un - 1 + .085Un - 1 becomes
Un( 1 + .085) + ( -1 - 1) which becomes
1.085Un - 2
I will leave the second one to you.
