Answer 1

Answer:

-11a²-11b²-122ab

Answer 2

Answer:

Step-by-step explanation:

25(a - b)^2 - 36(a +b)^2

According to rule of BODMAS,

We will do bracket first,

So,

25a^2 - 25b ^2 - 36a^2 + 36b^2

Then join the like terms,

25a^2 - 36a^2 -25b^2 + 36b^2

So, the answer will be

11a^2 + 11b^2

Hope, the explanation will help.
