Answer 2

Answer:

-10y + 12z² - 11z

Step-by-step explanation:

$- 2y {}^{3} + 3 {z}^{2} + 9 {z}^{2} - 8y {}^{3} + y {}^{3} - 11 {z + y }^{2} \\ - 2y {}^{3} - 8y {}^{3} + y {}^{3} + 3 {z}^{2} + 9 {z}^{2} + {y}^{2} - 11z \\ - 11 {y}^{3} + {y}^{3} + 12 {z}^{2} + {y}^{2} - 11z \\ - 10 {y}^{3} + 12 {z}^{2} + y ^{2} - 11z \\ - 10y + 12 {z}^{2} - 11z$

Hope my answer helps you buddy!

Have a nice day!
