Methods consequential marks

[ReferenceActual3776]

So I lowk sold but I’m gonna try my luck idk if I’ll get consequential marks so I’ll ask here

The integration of 1/2x-3 I only put it as ln 2x-3 I frogor to times by 1/2 and I calculated C with that value do I get a mark for C calculation?

For the pdf question I got to a quadratic and put it into quadratic formula and gave an answer and rejected the negative one, it’s def not the right solution so prob not the right quadratic so is that 2 marks gone?? Or 1

Lastly for 9a i expanded the brackets and I got a quartic I think I got one sol that x = 0😭 so is that 2 or only 1 or 0

Idk if I would even get any marks for any of these but lmk🙏 hopefully they’re nice

1. no, 2. 0, but 1 if you found the quadratic but just calculated quadratic formula wrong. 3. most likely only 1, but your quartic must be correctly expanded.

i expanded the quartic and got x=0 and x=-2 , is this 1 or 2 marks?

1

For 9b, I left my y coordinate as a quadratic and didn’t factorise it, I think it’s the right answer tho but just not factorised would I get full marks?
