x%5E2%2B5=13 Start with the given equation.


x%5E2=13-5Subtract 5 from both sides.


x%5E2=8 Combine like terms.


x=0%2B-sqrt%288%29 Take the square root of both sides.


x=sqrt%288%29 or x=-sqrt%288%29 Break up the "plus/minus" to form two equations.


x=2%2Asqrt%282%29 or x=-2%2Asqrt%282%29 Simplify the square root.

Answer:


So the solutions are x=2%2Asqrt%282%29 or x=-2%2Asqrt%282%29.
