partial-fractions-two-ways-to-find-the-constants-kristakingmath

► My Integrals course: https://www.kristakingmath.com/integrals-course

In this video I show two different methods for finding the constants in a partial fractions decomposition. The first, and more complicated way, is to set up a system of simultaneous linear equations, and then use substitution or elimination to solve to the system. The second, and simpler way, is to find the value that will zero out one constant so that you can solve for the other.

The simpler way only works in specific instances, which is why I prefer to stick to the first method, the system of linear equations, which is guaranteed to always work.

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.

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral
