Question 395137
Your solution is good!
Remember that there is only one number whose square equals the number itself, and that is 1 since:
{{{1^2 = 1}}} so the solution to:
{{{x^2 = x}}}
{{{x*x = x}}} Divide both sides by x.
{{{cross(x)*x/cross(x) = cross(x)/cross(x)}}} leaving you with:
{{{x = 1}}}
