Question 187620
{{{x^2+10=35}}} Start with the given equation.



{{{x^2=35-10}}} Subtract 10 from both sides.



{{{x^2=25}}} Combine like terms.



{{{x=0+-sqrt(25)}}} Take the square root of both sides (don't forget the "plus/minus").



{{{x=sqrt(25)}}} or {{{x=-sqrt(25)}}} Break up the "plus/minus" to form two equations.



{{{x=5}}} or {{{x=-5}}}  Take the square root of {{{25}}} to get {{{5}}}.



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



Answer:



So the solutions are {{{x=5}}} or {{{x=-5}}}.
