Me being absent one day from school and skipped this topic. The teacher won't explain it again so I had to look through youtube for this.. and for sure I am grateful for this video😌🙂
Asad, it is because otherwise it would be an improper fraction. We are trying to break down the original fraction into simpler fractions...hope that helps!

Easier method to do this in case it helps anyone. - Don't expand the bracket and group the coeffs, just look at the power. - In (Ax+B)(x+3) + C(X^2+2), you can see without doing anything with it that A and C are the only ones that are coeff of x^2 (power deg 2). - The other side has 5x^2, so you just get 5 = A + C right away. You can use the same trick for deg 0 to easily get 7 = 3B +2C. - Now, sub in x = -3 so (Ax+B)(x+3) = 0, from this you get 22 = 11C => C = 2. - Then you sub C into the first two coeff equations you got.
This is a good explanation however I don’t like the fact that he didn’t explain why he made the numerators Ax+ B and C and when he came down to the bottom. Why did he multiply the brackets by -3. That doesn’t give much clarity to those who are doing the topic for the first time
There are many examples out there and you should start on the basic rules and concepts of partial fraction decomposition and the -3 at the bottom is to balance (or subtract) the positive 3A so that you could get nearer to its values for numerator

Thorough and precise. Something my professor in an hour of lecture could never pull off. You have my sincere gratitude.
just wanna give a huge thanks because you teach this information well and very clearly. you deserve all the praise in the world
Thanks a lot! Glad my video was helpful for you!
0.33 “numerator to be one degree lower” such a small thing but i am in your debt forever sir
Thank you for being so thorough!

@@MariosMathTutoring Thank you so much! You honestly are a God-send! I'm so thankful for your work!
Very helpful. Thank you very much. Loved the simple and clear presentation
You’re welcome Jaden! Glad you liked the video!
did you made part 2? to solve this further by putting values in constants (Ax+b) & C , then integrate
how could people dislike this guy videos...love his videos
Thanks Floyd!
THANK YOU MARIO MY PROFFESSOR TAUGHT ME THIS FOR EVER AND I DIDNT UNDERSTAND UNTIL THIS VDO
Thank you very much. It really helped in solving integrals 😅
Glad it helped!
Thank you very much Sir, saved a lot of time.
This just helped so much. Thank you !!
Glad it helped!
very well explained ...
finally i can solve it without any problem😃
thankyou..
+Deepali Sharma I'm glad the video helped you understand the topic better.-Mario
Thank you so much your videos are a big help. Can you perhaps make one with partial decomposition tricks with few examples pleaze.
Explained it so much better than my calc professor
Great! Glad my video helped you...

Sir, plz tell why we pur Ax+B in the numerator, i.e why we put a polynomial having a degree less than denominator.

True but, A / x^2 + 1, might also be done to make it proper fraction
thank you, very helpful
Thanks mario to have a complete concept
Your welcome Nishant!
Very nice explanation thanks!
Glad you liked the video David!
Even better the second time!
What if you have 1 in the numerator. for example I had intgral e^x/(e^2x-4)^2
then u sub u=e^x du=e^xdx
1/(u^2-4)^2 du
thank you so much you cleared up my thoughts about this :) like and subbed
Glad my video helped you Mahamad. Welcome to the channel.
good explanation!
Thank you so much...very helpful
You’re welcome!
thank you to teaching point by point
+bibhuti chandra bharti your so welcome!
Thank you so much prof 🖤🖤
You’re welcome!
can this method only be used when there is 3 values on the numerator, but cant be used for equations such as 5x^2 +7 / (x^2+2)(x-1)
As far as I know it can be used regardless of how many terms are in the numerator...

Thank you so much 😀😀
You’re welcome James!
Thank you, it's very useful
Glad you liked the video!
Very well explained i understood it so well. But i wonder why you used equal instead of identity
excatly
thank you, very clear :)
Glad to hear that!
thanks.
Thank you so much !
You’re welcome Amr!
Thank you so much Sir
You’re welcome! Glad you liked the video!
please clarify on why you are multiplying the equations by -3, why negate 3?

The two videos have made everything clear tome, thankyou.
+Hilary Okoth your welcome
Great video
Glad you liked the video Richie!
thank you sir you saved me hehe...
Thanks sir
My first time being clickbaited on a maths video
Well played sir
you're a god
Glad my videos are helping you Matthew!
What if it was: x² * (x-1) ??
Thanks for your videos, really helpful!!! Keep it going!!!!!
very nice
ty
You’re welcome Oliver.
how to do if the numerator is 1
What if there were double different quadratic factor say(x^2+2)(x^2+3)
Easy Science think it’s just Ax+b and Cx+D then
damn he is amazing
Easier method to do this in case it helps anyone.
- Don't expand the bracket and group the coeffs, just look at the power.
- In (Ax+B)(x+3) + C(X^2+2), you can see without doing anything with it that A and C are the only ones that are coeff of x^2 (power deg 2).
- The other side has 5x^2, so you just get 5 = A + C right away. You can use the same trick for deg 0 to easily get 7 = 3B +2C.
- Now, sub in x = -3 so (Ax+B)(x+3) = 0, from this you get 22 = 11C => C = 2.
- Then you sub C into the first two coeff equations you got.
Help, I can't seem to understand the different terms used to get a b c huhu

Pls help with math problem
Good
Why multiply -3
2 hour or 5 minutes? 5 minutes is enough
mantap botak
it's -5 not -15 T_T
thanks sir
