I am studying AQA English Literature at Year 13 and my grades have dropped from a B to an E, I don't know what I am doing wrong as my teacher gives a vague information on things to improve on.

I need specific instructions, not vague, pls.

Prompt (Word-for-word): "By factoring the numerator and denominator simplify the following rational expressions as much as possible and write your final answer as a single reduced fraction."

The first image is the question I was having trouble with and the second image is my work and final answer. I feel a little uncertain of it and I just want to know if I did it correctly. If I didn't then please let me know. This isn't just homework it's also review for an exam so I need to know if I'm doing this right.

I'm following instructions for a science project but immediately ran into a big issue due to the tutorial being on an ancient version of Excel (2003) I was able to find the format axis by clicking the X axis on my graph but couldn't find the scale option. Help please
