We can simplify rational expressions by crossing out factors from the top and bottom that are exactly the same. If two binomial factors seem very close, but not exactly the same, it could be that you're needing to re-write opposite binomial pairs. Try factoring out negative one from one of the binomials and perhaps re-ordering the terms (if it's a sum.) Often the new binomials can be canceled out- but don't lose the negative one that you introduced!
