checking work polynomials

[kramer65gto]

2b-28a²b+10ab
-28a²b+10ab+2b
-2b(14a²-5a-1)
-2b(7a+1)(2a-1)


Is this finished properly?
again thanks for the help.

If your factorization is correct - it is now reduced to simplest terms.

To check "correctness" of your factorization - multiply your answer out using distributive law (FOIL). Then compare the answer with the given polynomial. If those two are equal - you are most probably correct.

I've checked, it's correct.
