2y%5E2-50=0 Start with the given equation.


2y%5E2=0%2B50Add 50 to both sides.


2y%5E2=50 Combine like terms.


y%5E2=%2850%29%2F%282%29 Divide both sides by 2.


y%5E2=25 Reduce.


y=%22%22%2B-sqrt%2825%29 Take the square root of both sides.


y=sqrt%2825%29 or y=-sqrt%2825%29 Break up the "plus/minus" to form two equations.


y=5 or y=-5 Take the square root of 25 to get 5.


--------------------------------------


Answer:


So the solutions are y=5 or y=-5.
