It is difficult to be certain about your question because of limitations of the browser used by Answers.com: we cannot see most symbols. If this answer addresses the wrong equation, please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared".
-1/2x2 - 1/2x + 6 = 5
Multiply by -2 : x2 + x - 12 = - 10 or x2 + x - 2 = 0
Factorising: (x + 2)(x - 1) = 0
So x + 2 = 0 or x - 1 = 0
therefore, x = -2 or x = 1
