Answer:
![9 {x}^{2} - 3x](https://tex.z-dn.net/?f=9%20%7Bx%7D%5E%7B2%7D%20%20-%20%203x)
Step-by-step explanation:
We want to simplify
![(5 {x}^{2} + 2) - ( - 4 {x}^{2} + 7) + ( - 3x - 5)](https://tex.z-dn.net/?f=%285%20%7Bx%7D%5E%7B2%7D%20%20%2B%202%29%20-%20%28%20-%204%20%7Bx%7D%5E%7B2%7D%20%20%2B%207%29%20%2B%20%28%20-%203x%20-%205%29)
We expand the parenthesis to get;
![5 {x}^{2} + 2 + 4 {x}^{2} - 7- 3x - 5](https://tex.z-dn.net/?f=5%20%7Bx%7D%5E%7B2%7D%20%20%2B%202%20%20%2B%204%20%7Bx%7D%5E%7B2%7D%20%20%20%20-%20%207-%203x%20-%205)
We group similar terms to get:
![5 {x}^{2} + 4 {x}^{2}- 3x - 5 + 2 - 7](https://tex.z-dn.net/?f=5%20%7Bx%7D%5E%7B2%7D%20%20%2B%204%20%7Bx%7D%5E%7B2%7D-%203x%20-%205%20%2B%202%20-%207)
Combine the terms;
![9 {x}^{2}- 3x + 0](https://tex.z-dn.net/?f=9%20%7Bx%7D%5E%7B2%7D-%203x%20%20%2B%200)
Therefore the simplified expression in standard form is:
![9 {x}^{2} - 3x](https://tex.z-dn.net/?f=9%20%7Bx%7D%5E%7B2%7D%20%20-%203x)
Answer:
