Hi
Great videos
If the question says use algebraic division do we have to use it or is it - use any method as long as you get the correct answer?
I think about what it is going to look like using A, B and C for coefficients, multiply through by the denominator and then compare coefficients etc (like your second example)

hi sir, I'm a bit confused about the side note at 14:50, would it be correct to say that the rule here is that the highest degree in the numerator needs to be one less than the highest degree in the denominator? thank you so much!!

If we fully understand the first method is it necessary to know the second? I don’t do fm by the way. Thank you

In the side note, how do we know that it would be cx+D, why can’t it be Bx+C. Because I rlly don’t understand y it’s Ax + B + cx+D, how would I know that it’s not Ax + (Bx+C) + D instead? Weird question but hopefully u understand my question

Sorry, in the side note at 15:42, when you say the numerator has to be the most general thing that could be above it, what do you mean exactly? Thank you.

When doing the identities method will it always be the same so A+B/x+1 + C/x-2 ?

Hi Sir, how do you know when to stop doing algebraic division e.g. for first example why did you stop at 6x-8 ?

When we have Denominator with higher degree. Which case is that? How should be my approach? Thanks

15:51 surely it would be 3+3-2 =4 so ... B = -4?

[shadowfatemahir]

What if the question was repeated root and improper at the same time. Such as the first question in this video, the denominator being (x-1)^2

Hi, in the exam would you lose marks if you put '=' instead of the equivalence symbol? Ive seen exam questions use it

Why at 6:57 do you put -A instead of A
