Answer:
"5 times the sum of a squared and b minus 3 times the sum of
a and b".
which can be simplified such as:
![5\left(a^2+b\right)-5\left(a+b\right)=5a^2-5a](https://tex.z-dn.net/?f=5%5Cleft%28a%5E2%2Bb%5Cright%29-5%5Cleft%28a%2Bb%5Cright%29%3D5a%5E2-5a)
Step-by-step explanation:
Given the verbal expression
"5 times the sum of a squared and b minus 3 times the sum of
a and b".
BREAKIN DOWN THE STATEMENT:
The sum of 'a' Squared and 'b' = a²+b
- 5 times the sum of a squared and b = 5(a²+b)
The sum of a and b = a+b
- 3 times the sum of a and b = 5(a+b)
Now, "5 times the sum of a squared and b minus 3 times the sum of
a and b".
Let us simplify the algebraic expression
![5\left(a^2+b\right)-5\left(a+b\right)](https://tex.z-dn.net/?f=5%5Cleft%28a%5E2%2Bb%5Cright%29-5%5Cleft%28a%2Bb%5Cright%29)
![=5a^2+5b-5a-5b](https://tex.z-dn.net/?f=%3D5a%5E2%2B5b-5a-5b)
simplify
![=5a^2-5a](https://tex.z-dn.net/?f=%3D5a%5E2-5a)
Thus,
![5\left(a^2+b\right)-5\left(a+b\right)=5a^2-5a](https://tex.z-dn.net/?f=5%5Cleft%28a%5E2%2Bb%5Cright%29-5%5Cleft%28a%2Bb%5Cright%29%3D5a%5E2-5a)
