Answer 2

Answer:

4. Given  

how much is zero greater than minus A square minus a b + 7 b square

We need to find zero greater than minus A square minus a b + 7 b square

We can write in the form of an equation.

It will be 0 > - a^2 – ab + 7 b^2

So we have 0 – ( - a^2 – ab + 7 b^2)

Now we get the equation as a^2 + ab – 7 b^2
