Answer 2

Answer:

-5a2+0.3b2-10

Step-by-step explanation:

−2.3a2+1.3b2−2.7a2−10−b2

First, match the terms;

−2.3a2−2.7a2+1.3b2−b2-10

Now Simplify it;

−2.3a2−2.7a2 = (minus into minus) −5a2

+1.3b2−b2 (1b2) = +0.3b2

-10 remains the same.

Now write it together;

-5a2+0.3b2-10

That's how you simplify it.

You can't simplify it more as you don't know the value of a and b.

Hope this helps ^^
