Question

7 times the sum of a squared and b minus 4 times the sum of a squared and b

Answer 1

(7•((a^2)+b))-(4•((a^2)+b))

Answer 2

Let's solve this problem step by step.

First. The sum of a squared and b

`a^2+b`

Second. 7 times the sum of a squared and b

`7(a^2+b)`

Third. 4 times the sum of a squared and b

`4(a^2+b)`

Finally. 7 times the sum of a squared and b minus 4 times the sum of a squared and b

`7(a^2+b)-4(a^2+b)`

And this is:

`\boxed{7(a^2+b)-4(a^2+b)=3(a^2+b)}`
