2x%5E2=200 Start with the given equation.


x%5E2=%28200%29%2F%282%29 Divide both sides by 2.


x%5E2=100 Reduce.


x=%22%22%2B-sqrt%28100%29 Take the square root of both sides.


x=sqrt%28100%29 or x=-sqrt%28100%29 Break up the "plus/minus" to form two equations.


x=10 or x=-10 Take the square root of 100 to get 10.

Answer:


So the solutions are x=10 or x=-10.
