Answer 2

It seems like you've provided a mathematical expression, but it's a bit unclear due to the formatting. I'll do my best to help you interpret and simplify it:

The expression you've given appears to be:

(2/3)a^2 - b^2 + (4/3)a^2 - (5/7)b^2

Let's combine like terms:

(2/3)a^2 + (4/3)a^2 - b^2 - (5/7)b^2

To combine the terms involving 'a^2', add the coefficients: (2/3 + 4/3)a^2 = (6/3)a^2 = 2a^2

To combine the terms involving 'b^2', subtract the coefficients:

• b^2 - (5/7)b^2 = - (7/7)b^2 - (5/7)b^2 = - (12/7)b^2

So, the simplified expression is: 2a^2 - (12/7)b^2
