    you only "solve" equations (which have an equal sign in them) do you mean add and simplify?

    you have two fractions. to add fractions you need a common denominator. to find the simplest common denominator I would first try to factor both denominators. For example, can you factor s^2+6s+9 ?

    when you see something like s^2+6s+9 you should think: can I write this as (s+a)(s+b) ? where a and b are numbers.

    one strategy to factor is to first look at the last number, the +9 the + means both factors (i.e. the a and b in (s+a)(s+b) are the same sign) for the 9, list all ways to multiply 2 numbers to get 9: 1,9 3,3 are the only choices.

    next, look at the middle number, the +6 from s^2+6s+9 the + sign in front of the 6 means the biggest factor of a and b is positive. from the first rule (up above) we know both are the same sign. so if one is positive and both have the same sign , both are positive. now go to our list 1,9 3,3 assign both a positive sign and add 1+9= 10 3+3= 6 if any pair matches the +6 from the middle term, those are the factors.
