This 'about me' will probably be updated when I have the time to edit every site-profile manually, and when I can be more active on the network.

Till then, this remains a placeholder account with all of my previous questions, comments, and whatever else is tied to my alias on SE.

comment Signs in binomial expansions
Thank you; the gears clicked into place! Once the exams are over, I'll put on an answer that's -hopefully- as intuitive as I get it now.

That doesn't tell why it was decided (apparently, that's how I was given it) that such terms, at face value, need the expansion with opposite signs. I added an (*) in the \$\$ so see there for what I meant.

@KannappanS, Discriminant! I wrote it the other way as I remembered its pronunciation in class... So many faults in my educational system... Anyway, it's ($\Delta = b^2-4ac$).

He asked for my trial on the second one and so I did... I never intended it to be un-respectful and I knew it doesn't work in questions yet I only wanted it visible as the answer he requested.

I tried it with the second and can't get the $x$ and $n+3$ out... Where can I post a photo?

Can't delete prev. comments. - @JohannesK, Isn't Vieta's formula where we use a discrement to extract the roots? I tried but that didn't work.

@GerryM, I'd said it was weird from the get go... It did actually use different case letters! - It's from my curriculum book, 10th grade equiv., Egypt.

But that would make $9a^2c = 2b^2$ which isn't the answer provided. It does seem logical and correct in steps but here they look for how good you followed the book even if it's incorrect. So I just need a confirmation that there's no other way to re-produce the answer provided. - I'll follow your steps and post the second one.
