Can you please help me factor this trinomial...?

Question

x^3m^2 - 5xmn - 14xn^2

When I took out the common factor which is x

x(x^2-5mn-14n^2), i think this is as far as I can factor them...

Answer 1

you forgot some stuff when you did the common factor:

x (x^2m^2 - 5mn - 14n^2)

that is as far as you can go with this (assuming you haven't made an error with the question)...the x^2 causes problems
