x%5E2%2B7=7 Start with the given equation.


x%5E2%2Bcross%287-7%29=7-7 Subtract 7 from both sides.


x%5E2=0 Combine like terms.


x=%22%22%2B-sqrt%280%29 Take the square root of both sides.


x=sqrt%280%29 or x=-sqrt%280%29 Break up the "plus/minus" to form two equations.


x=0 or x=-0 Take the square root of zero to get zero.


Because negative zero is really zero, this means that there is only one solution which is x=0.
