I have included two different methods here, one of which is the standard long division and the other does not require long division.

I posted a qns, can u show me using sum of root and product of root
Do you have any method same as the Long division for this qns?
The two methods in this case work. I am not sure how Long division actually works (the idea behind it), but both methods are actually related. You know how Long division works right?
I sometime Long division will miss out. So I worry
I doubt there are other methods to do those questions (at least to my knowledge). Long division is still the fastest way to get the answer, and is needed when you lean graphing techniques if you are going into jc.
Ok
You can solve it as an identity question the way I present it. After all, the denominators must be the same so you can multiply all sides by the denominator to get rid of the denominator. When you do partial fractions, we also get rid of the denominator in a similar fashion.
