I'm not entirely sure what you're asking for; what d'you mean "arrange properly"?

If you mean simplify the expressions then you need to first multiply out the brackets.

[Papershop]

if your asking for this

t x t+b(s-1)+(s-1)
=>t x t + b.s - b + s - 1
=>tsqaured+tbs-bt+st-1

Im doing this in class at, but I DONT understand what your saying? lol.
