+m%5E2+-+%2825%2F2%29%2Am+=+5%2F2++
+m%5E2+-+%2825%2F2%29%2Am+%2B+%2825%2F4%29%5E2+=+5%2F2+%2B+%2825%2F4%29%5E2+
+m%5E2+-+%2825%2F2%29%2Am+%2B+625%2F16+=+40%2F16+%2B+625%2F16+
+%28+m+-+%2825%2F4%29+%29%5E2+=+665%2F16+
Take the square root of both sides
+m+-+25%2F4+=+sqrt%28665%29+%2F+4+
+m+=+%28+25+%2B+sqrt%28665%29+%29+%2F+4+
and
+m+=+%28+25+-+sqrt%28665%29+%29+%2F+4+

maybe all you got wrong is a sign?
