-9а^2-13,5а^2-2

Answer 2

Sure, I'd be happy to help you simplify the expression!

The expression you provided is:

-0.5 * (6a^2 + 1) * (3a^2 + 4)

To simplify it, we can start by using the distributive property of multiplication over addition:

a * (b + c) = a * b + a * c

Now, let's apply the distributive property to the given expression:

-0.5 * (6a^2 + 1) * (3a^2 + 4) = -0.5 * 6a^2 * (3a^2 + 4) -0.5 * 1 * (3a^2 + 4)

Now, we can simplify each part separately:

-0.5 * 6a^2 * (3a^2 + 4) = -3a^2 * (3a^2 + 4) = -9a^4 - 12a^2

-0.5 * 1 * (3a^2 + 4) = -0.5 * (3a^2 + 4) = -1.5a^2 - 2

Now, combining the two simplified parts:

-9a^4 - 12a^2 - 1.5a^2 - 2

Finally, let's combine like terms:

-9a^4 - 13.5a^2 - 2

So, the simplified expression is:

-9a^4 - 13.5a^2 - 2
