    It is a quadratic equation where x^2 = y. Use the quadratic formula to figure the roots.

    but then you have u^2 - 11u + 1 which won't factorise

    don't rely only on "factorizing" by ease. Quadratic formula does generate factors you know.

    it will factorize, \[b^2-4ac >0\]

    lol..this is strange as the solution is \[(x + (11 +\sqrt{117})/2) (x + (11 - \sqrt{117})/2)\] lol...

    :) Not all factors are "clean as a whistle integers". In real life, they are even worse.
