Question 766065
Raise each side to the (1/2) power, and have two equations:


{{{x+5=+- y^2}}}---------the rendering is failing.  Supposed to say plus or minus.
{{{x=+- y^2-5}}}---------the rendering is failing.  Supposed to say plus or minus.


...
Or you could turn that around to get y as a function of x.
{{{y^2=-(x+5)}}}  OR  {{{y^2=x+5}}}
{{{y^2=-x-5}}}   OR  {{{y^2=x+5}}}
{{{highlight(y=-sqrt(-x-5))}}}  OR  {{{highlight(y=+ sqrt(x+5))}}}
