X^2-3x-3 factorise it without using shroud jara chara method
Well, old chap, a reasonable request would be to Factor x2-3x-3
and for the past century, I think most of us old timers would quickly decide that it's prime. (Proof of that would be to calculate the discriminant, which will be (-3)2 - 4(1)(-3) = 9 + 12 = 21. Since the discriminant's square root is irrational, this quadratic is not factorable.
As to the "shroud jara chara method" reference, I am betting that few, if any, know what that is. (Could it be some extreme mumbo jumbo emanating from the Common Core nuttiness?)
