Pre-Calculus - Partial fraction decomposition

[samanthastanley]

I clicked on your video to learn how to find the coefficients. You didn't include the most important part.

[LoadsOfStacks]

All of your pre call videos have helped me so far. I have a college final tomorrow. Hopefully I'll do good, I need it.

[taratara]

why you skip?....i really need a step of how to get those coefficient. Thanks

[wizkoko]

This video is not for people who are learning this from scratch. It is for those that know it but have forgotten how to do it. In short, the whole video is just a quick revision. So if you are learning this from scratch, I suggest you find another video.

I wish there was a video to do both the Partial Fraction Decomposition and the Solving for Coefficients...

[muhammadrashidpk]

why you skip video solved system coefficient A=4
B=4
C=-4
D=4

[raymarbartolome]

How did you get the value of A, B, C and D?

[RkMaliksNewtonClasses]

It is very long method
It can be done by a method much more shorter than given method

[Gershonn]

Finally found a system with four equations. Whew!

[Ben-wvsk]

U solve that system of equations first because am not understanding it

[TheCsePower]

This is why I hate Mathematics. All you do is learn by heart a couple of nonsense formulae to apply them later.

I hope you included the most impossible part 😥 I find myself missing now. I can't solve the given problem I have . Coz I need to know this"system of equation" stuff.
Anyways..could anyone tell me what to do if the numerator is bigger than the denominator (factors below)?

[Nickinthefrozennorth]

If the denominator is say (3x +1) squared, why do you have 3x +1 for one denominator and (3x+1) squared for another denominator?

[henrikbergvallberglund]

In the first expression where you set: A(x²+3) + B(x+2)(x²+3)... I see that some factors disapear, like in the first term with: A(x²+3), shouldnt there be a factor here with (x+2) also, from the denominator under B? Same goes for the other two terms, one factor each disapear. This has something to do with how they cancel out if you put the denominator under the whole expression. But if you do this doesnt this make a change in the whole expression from start? If you get how i mean. :)

Can you please set this so that users can contribute captions, or, better yet, verify the captions and mark them as not auto generated?

[bonnieamof]

I love ur way of explaining it ing general, especially when it came to figuring out the top coefficients of A, B, ect.

[normtheclone]

What if after factorizing and separating the fraction, you end up with a denomenator of the form (x^4+n). Would the corresponding numerator have the form (Ax^3+Bx^2)? or would it be (Ax^3+B)?
Similarly, would a denominator of the form (x^4+x^3+n) correspond to a numerator of the form (Ax^3+Bx^2+C)? Or something else?
Please someone help me!!!

I not understend very good english, but i understend that you do, i need know how used that constants when is lineal or quad, thanks so much... i hope you understend my english, really thanks

[awgmohd]

where the hell that you get A=4, B=4, C=-4, and D=4? can someone explain to me

[eipimath]

Thanks for sharing! I posted a video on partial fractions with repeated linear factors. Hope to get your thoughts.
