You can put this solution on YOUR website!
I notice that:
+11%2A4+=+44+ and
+11+%2B+4+=+15+
---------------------
Using this:
+z%5E2+-+15z+%2B+44+=+%28+z+-+4+%29%2A%28+z+-+11+%29+
-----------------------------------------
+5x%5E2+-+125+=+5%2A%28+x%5E2+-+25+%29+
+5%2A%28+X%5E2+-+25+%29++5%2A%28+X+-+5+%29%2A%28+X+%2B+5+%29+
-----------------------------------------
Hope this makes sense
