%282x-3%29%5E2=9 Start with the given equation.


2x-3=%22%22%2B-sqrt%289%29 Take the square root of both sides.


2x-3=sqrt%289%29 or 2x-3=-sqrt%289%29 Break up the "plus/minus" to form two equations.


2x-3=3 or 2x-3=-3 Take the square root of 9 to get 3.


2x=3%2B3 or 2x=3-3 Add 3 to both sides.


2x=6 or 2x=0 Combine like terms.


x=3 or x=0 Divide both sides by 2 to isolate x.

Answer:


So the solutions are x=3 or x=0.
