Question 851512
sqrt(-5a+6)=-a


Putting triple left braces on the left and triple right braces on the right, renders as this:      {{{sqrt(-5a+6)=-a}}}


Square both sides, simplify, and you can solve for a.


{{{(sqrt(-5a+6))^2=(-a)^2}}}
{{{-5a+6=a^2}}}
{{{-a^2-5a+6=0}}}
{{{a^2+5a-6=0}}} and the left side is factorable.
