I think this is what you need:

Step 1: Simplify the radical.

Step 2: Factor the numerator.

Step 3: Reduce the fraction.

I'll illustrate with your own example:x%5E2+-8x-3+=+0
You come up with x = +%288%2B-sqrt%2876%29%29%2F2+

Step 1: Simplify!
+%288+%2B-sqrt%284%29%2Asqrt%2819%29%29%2F2
+%288%2B-+2+%2Asqrt%2819%29%29+%2F2+

Step 2: Factor!
%282%284%2B-sqrt%2819%29%29%29%2F2

Step 3: Reduce!
4%2B-sqrt%2819%29
