Let's solve this problem step by step.


First. The sum of a squared and b

[tex]a^2+b[/tex]


Second. 7 times the sum of a squared and b

[tex]7(a^2+b)[/tex]


Third. 4 times the sum of a squared and b

[tex]4(a^2+b)[/tex]


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

[tex]7(a^2+b)-4(a^2+b)[/tex]


And this is:

[tex]\boxed{7(a^2+b)-4(a^2+b)=3(a^2+b)}[/tex]
