You could solve this by factoring:
x%5E2%2B6x%2B9+=+0
The factors will be of the form:
%28x%2Bm%29%28x%2Bn%29=0 where m*n = 9 and m+n = 6
There is only one value of m and n that will work; m = 3 and n = 3, so you get:
x%5E2%2B6x%2B9+=+%28x%2B3%29%28x%2B3%29 so...
%28x%2B3%29%28x%2B3%29+=+0 and x+=+-3
