Given a rational function (the ratio of two polynomials, or a fraction with a polynomial numerator and denominator), and asked to find the limit of the rational function, you may be able to solve for the limit by factoring the rational function.
Oftentimes just using substitution will result in a 0/0 value. Instead of trying L'Hospital's rule right away to take care of the indeterminate form, consider instead whether or not you can factor the numerator and/or denominator. You may be able to find a common factor between them, cancel it out of the fraction, and end up with a limit you can actually solve.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)
Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”
So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
