We taking the square cause we need absolute value of distance. I don't understand your second question. If it's about taking deriviative try to look "Single variable calculus". If about simplifying just open brackets.

we can remove the 2 because we are setting the partials equal to 0. Therefore we can divide both sides by 2.
