Question 70671
Rewrite the middle term as the sum of two terms and then factor completely.
12w^2 + 19w + 4 

The answer I got for this problem was:
12w^2 + 3w + 16w + 4

Is this correct? Thanks
COMMENT: Yes, it is correct.

4z^3 - 18z^2 - 10z

The answer I came up with for this problem was:
(2z)(2z^2 - 9z - 5)

Is this correct? Thanks
COMMENT: You are not yet finished.
The two middle terms are the following. 

= 2z(2z^2-10z+z-5)
