Finding Real Numbers: Questions (c) & (e) Solutions

[Apple&Orange]

Homework Statement

Please see questions (c) and (e) on the attachement

2.Relevant Equations

The Attempt at a Solution

So long story short, these two questions were given out as a challenge in one of our Swedish lessons to see if we could remember our high school calculus, which I shamefully have to admit I cannot.

I've done a search through the forums but unable to find any relevant information that could help me solve these equations.
If anybody is willing, could someone post links, or steer me in the right direction that could help me solve these?

Do you remember the binomial formula for $(a+b)^2$ and long division by hand?

I (and most other helpers) refuse to help you because you post a sideways image instead of typing out the problem. I can see an (almost-unreadable) image on my laptop computer, but cannot see anything at all on my i-phone.
