The discriminant is less than 0 so the equation has no real roots and therefore, no real factors.
If by "what is the answer to" you mean "how do you factor", then the answer is as follows: x2 + 52x + 100 = x2 + 50x + 2x + 100 = x(x + 50) + 2(x + 50) = (x + 2)(x + 50)
(2x + 1)(x - 5)(x + 5)
x3 + x2 + 4x + 4 = (x2 + 4)(x + 1)
x + 4
x2(x3 + 1) is the best you can do there.
Factor x2 plus 12xp plus 36p2 is (x+6p)(x+6p).
You can't factor it
That does not factor neatly.

Not factorable
x2 + 5x - 120 can not be factored.
x2+10x-336
