Type out the question, I have another method instead of long division, its the bracket method so much easier and quicker, but needs practice

You can rotate it before you upload
As for the question, your +11, turned into a -11. . . though you may have made another mistake, I've not checked

okay, it's actually a partial fractions questions but as it's a top heavy fraction we got told to use the long division so would mind telling me that way, because that's the way i got taught please?

the question is:
Express 2x^2 -x-11/ (2x-3)(x+2) in the form A+ B/2x-3 + C/x+2

Firstly, not 0

Haha it was the right way but then when i uploaded it it rotated
ahh yeah true, thanks!

In that case you just need that from your long division

Then do your partial fractions work knowing that A = 1

yeah sorry my bad, but then the remainder would be -2x+17 right?

For partial fractions like that I'd do it by a bit of algebraic manipulation but then again I'm weird

oh okay i see, thank you!

But that is irrelevant you only need the long division to get A = 1

Which, tbh you should just be able to see

You can split it so that you just use the remainder for your partial fraction work but that is messy and prone to errors

I like the bracket method. Its the best (you mean the factorisation starting from 3rd line back to filling up in 2nd ?).

Only suitable if you are factoring, so not in this question

Yeah so like you have 2 brackets

( fill this is in) (what ever the original thing was)
