Question

(5a^{2}-11ac+8c^{2})+(-2c^{2}-7a^{2}+5ac)=

Answer 1

Объяснение:

(5а²-11ас+8с²)+(-2с²-7а²+5ас)=

=5а²-11ас+8с²-2с²-7а²+5ас=

= -2а²-6ас+6с²

Answer 2

To simplify the given expression:

(5a^2 - 11ac + 8c^2) + (-2c^2 - 7a^2 + 5ac)

We can combine like terms by adding the coefficients of the same variables. The variables in this expression are a and c.

The terms with "a^2" are 5a^2 and -7a^2. Their sum is 5a^2 - 7a^2 = -2a^2.

The terms with "ac" are -11ac and 5ac. Their sum is -11ac + 5ac = -6ac.

The terms with "c^2" are 8c^2 and -2c^2. Their sum is 8c^2 - 2c^2 = 6c^2.

Putting it all together, the simplified expression becomes:

-2a^2 - 6ac + 6c^2
