Simplify:
sqrt%28-50%29+-+sqrt%28-8%29 Factor the radicands.
sqrt%28-2%2A25%29+-+sqrt%28-2%2A4%29 Take the square roots of the perfect squares (25 and 4) and move them outside of their respective radicals.
5sqrt%28-2%29+-+2sqrt%28-2%29 Combine like-terms.
3sqrt%28-2%29 This can also be written as:
3sqrt%282%29%2Ai
