# C1 simplifying question watch

1. Simplify

1/4-sqrt5 + 1/4+sqrt5

I found the common denominator to be 11, but i was unsure how to progress from that. the answer is 8/11
2. I have scanned my working (sorry about doing it in colouring pencil, only one I had on me), lol...

Hope you can see what I did. =)

EDIT:
Just noticed on the second row, I wrote 2 4-swrt5's instead of 1 positive and 1 negative, honest mistake and I don't think it will kill you in the exam, worst case scenario (if being REALLY mean, lose 1 mark).
