first step: pull out any common factors:
3x^3-3x^2-18x =
3x(x^2 - x - 6) =
3x(x - 3)(x + 2)
5x^3 + 10x^2 + 25x =
5x(x^2 + 2x + 5)
25c^2 - 40c + 16 =
(5c - 4)(5c - 4)

1) Simplifying
3x3 + -3x2 + -18x
Reorder the terms:
-18x + -3x2 + 3x3
Factor out the Greatest Common Factor (GCF), '3x'.
3x(-6 + -1x + x2)
Factor a trinomial.
3x((-2 + -1x)(3 + -1x))Final result: 3x(-2 + -1x)(3 + -1x)
2) Simplifying
5x3 + 10x2 + 25x
Reorder the terms:
25x + 10x2 + 5x3
Factor out the Greatest Common Factor (GCF), '5x'.
5x(5 + 2x + x2)Final result:5x(5 + 2x + x2)
3) Simplifying
25c2 + -40c + 16
Reorder the terms:
16 + -40c + 25c2
Factor a trinomial.
(4 + -5c)(4 + -5c)Final result:(4 + -5c)(4 + -5c)
