$\bold{= > 2 {y}^{2} - 7y - 5 + 3y + 8 + 3 {y}^{2} + 4y - 9}$

=>take same term together with same degree to make our calculation easier.

$\bold{= > 2{y}^{2} + 3 {y}^{2} - 7y + 3y + 4y - 5 + 8 - 9}$

$\bold{= > 5 {y}^{2} - 7y + 7y - 5 - 1}$

$\bold{ = > 5 {y}^{2} -0- 6}$

$\bold{ = > 5 {y}^{2} - 6}$
