Access full lesson containing this video at: http://www.yourteacher.com/alg... Students learn that when adding rational expressions, the first step is to factor each of the denominators, if possible, then give each term a common denominator by multiplying the numerator and denominator of each term by the appropriate value. Next, add across the numerators and keep the denominators the same. Finally, factor the resulting numerator, if possible, to determine if the rational expression can be reduced.

people should care about what happens in the "third world" because we are one world that should care about equal opportunity... I know I CARE about equality and life all over the world because without people like me there would be no world.

He didn't factorize 5a-45 because 45 doesn't have a variable

I noticed he did not factor out 5a-45. Why not? It's factorable to 5(a-9).
