Answer:
The value of a is 150 and b is 4822.
Explanation:
First, you have to expand to remove brackets :
![(5372 + 100 {y}^{2} ) + 5(10 {y}^{2} - 110)](https://tex.z-dn.net/?f=%285372%20%2B%20100%20%7By%7D%5E%7B2%7D%20%29%20%2B%205%2810%20%7By%7D%5E%7B2%7D%20%20-%20110%29)
![= 5372 + 100 {y}^{2} + 50 {y}^{2} - 550](https://tex.z-dn.net/?f=%20%3D%205372%20%2B%20100%20%7By%7D%5E%7B2%7D%20%20%2B%2050%20%7By%7D%5E%7B2%7D%20%20-%20550)
Next, you have to simplify :
![100 {y}^{2} + 50 {y}^{2} + 5372 - 550](https://tex.z-dn.net/?f=100%20%7By%7D%5E%7B2%7D%20%20%2B%2050%20%7By%7D%5E%7B2%7D%20%20%2B%205372%20-%20550)
![= 150 {y}^{2} + 4822](https://tex.z-dn.net/?f=%20%3D%20150%20%7By%7D%5E%7B2%7D%20%20%2B%204822)
Next, you have to compare it :
![a {y}^{2} + b = 150 {y}^{2} + 4822](https://tex.z-dn.net/?f=a%20%7By%7D%5E%7B2%7D%20%20%2B%20b%20%3D%20150%20%7By%7D%5E%7B2%7D%20%20%2B%204822)
![a = 150](https://tex.z-dn.net/?f=a%20%3D%20150)
![b = 4822](https://tex.z-dn.net/?f=b%20%3D%204822)
