(adsbygoogle = window.adsbygoogle || []).push({}); basic algebra concept is puzzling me....

1. The problem statement, all variables and given/known data

I don't understand why √10-5 + √5 = 2√5

Could someone please explain this to me real quick...totaly forgot why this is :P

2. Relevant equations

none

3. The attempt at a solution

here I am! thoughts about it and I am still puzzled does it have anything to do with the fact that √10-5 =√5 and then we add another √5 to it and there is some rule that says that you take one of them away and just put a 2 infront of √5 and it is equivilant?
