To factorise this completely you need to be aware that 216 = 63.
(x3 + 216) = (x + 6)(x2 - 6x + 36)
You need to find a pair of factors of the ( -27 ) that add up to the ( 6 ).
+9 and -3 will do it.
x2 + 6x - 27 = (x + 9) (x - 3)
(x + 6)(x^2 - 6x + 36)
6(x + 6)(x + 6)
(x + 18)(x + 4)
(6x + 1)(x + 1)
6(x + 9)(x - 1)
x2 + 18x - 50 does not have rational factors.
(x + 4)(x + 8)
Assuming the question is written as: x2+11x-12 This would factor to: (x+12)(x-1)
(x + 5y)(x - 3y)
(x + 2)(x - 1)
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+10x-336
x2 + 5x - 120 can not be factored.
x2 - 13 + 30 = x2 + 17, which has no real factors.
x2 + 6x + 8 = (x + 4)(x + 2)
