Question

Factor 3c3 + 375.

–3(c + 5)(c2 – 5c + 25)
3(c + 5)(c2 – 5c + 25)
(c – 5)(c2 – 5c + 25)
(c + 5)(c2 – 5c + 25)

Answer 1

Ok so first take out a positive 3 not a negative 3, once you take out the 3 it should look like this:
Step 1: 3c^3+375=3(c^3+125)
Next you can divide everything by 3 and factor out whats in the parentheses
Step 2: (c+5)(c^2-5c+25)
