Answer 1

Ответ:

=11x³+18 2.-9x³-18 (1-e к первому )

Answer 2

To simplify the given expression, let's combine like terms:

-х² - 11х + 38 - 2х² + 7х - 18

To add or subtract quadratic terms, we combine the coefficients of the same degree terms. Let's combine the quadratic terms (-х² and -2х²):

(-х²) + (-2х²) = -3х²

Next, let's combine the linear terms (-11х and 7х):

(-11х) + (7х) = -4х

Finally, let's combine the constant terms (38 and -18):

(38) + (-18) = 20

Putting it all together, the simplified expression is:

-3х² - 4х + 20
