Answer:
i believe the answer is (3z - 4) • (2x + y)
Explanation:
Split 6xz + 3zy - 8x - 4y
into two 2-term polynomials
+ 3zy + 6xz and - 8x - 4y
This partition did not result in a factorization. We'll try another one:
6xz + 3zy and - 8x - 4y
This partition looks good
1.2 Pull out from each binomial separately
6xz + 3zy = 3z • (2x + y)
- 8x - 4y = - 4 • (2x + y)
1.3 Add up to arrive at the desired factorization
(3z - 4) • (2x + y)
