Answer and Step-by-step explanation:
44, 6, and 24 do not have perfect squares.
To be a perfect square, they have to be able to have a number that, when it multiplies itself by itself (needs to be a whole number), it turns into the bigger number.
44, 6, and 24 can't do this when being square rooted.
16 turns into 4.
81 turns into 9.
49 turns into 7.

Answer:
![y^2 + 8y + 16](https://tex.z-dn.net/?f=%20y%5E2%20%2B%208y%20%2B%2016%20)
Step-by-step explanation:
![(6y^2 + 2y + 5) - (5y^2 - 6y - 11) =](https://tex.z-dn.net/?f=%20%286y%5E2%20%2B%202y%20%2B%205%29%20-%20%285y%5E2%20-%206y%20-%2011%29%20%3D%20)
The first set of parentheses is unnecessary, so it can just be removed.
![= 6y^2 + 2y + 5 - (5y^2 - 6y - 11)](https://tex.z-dn.net/?f=%20%3D%206y%5E2%20%2B%202y%20%2B%205%20-%20%285y%5E2%20-%206y%20-%2011%29%20)
To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.
![= 6y^2 + 2y + 5 - 5y^2 + 6y + 11](https://tex.z-dn.net/?f=%20%3D%206y%5E2%20%2B%202y%20%2B%205%20-%205y%5E2%20%2B%206y%20%2B%2011%20)
Now you combine like terms.
![= 6y^2 - 5y^2 + 2y + 6y + 5 + 11](https://tex.z-dn.net/?f=%20%3D%206y%5E2%20-%205y%5E2%20%2B%202y%20%2B%206y%20%2B%205%20%2B%2011%20)
![= y^2 + 8y + 16](https://tex.z-dn.net/?f=%20%3D%20y%5E2%20%2B%208y%20%2B%2016%20)
