s/s^2+6s+9 + 5/s^2+4s+3 solve it
you only "solve" equations (which have an equal sign in them) do you mean add and simplify?
yes, sorry lol
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 ?
im horrible at algebra but i can try
6s^3+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.
can you factor s^2+6s+9 ?
too confusing ?
