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
For example, can you factor s^2+6s+9 ?
Not the answer you are looking for? Search for more explanations.
im horrible at algebra but i can try
when you see something like
you should think: can I write this as
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:
are the only choices.
next, look at the middle number, the +6 from
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
assign both a positive sign and add
if any pair matches the +6 from the middle term, those are the factors.
