green_1 · Answer

the answer is -2.4x^2-1.5x-11.4

anonymous · Answer

Combine like terms....Combine all the numbers that have X^2,  then combine all the numbers that just have x, finally combine all the numbers that are just numbers...

@ green_1
Perform the operation indicated, then place the answer in the proper location on the grid. Write your answer in descending powers of a.

By how much does a3 - 2a exceed a2 + a - 6?

here, we have to do this computations:
$-4.1+1.7=...?$
$0.9-2.4=...?$
$-9.8-1.6=...?$

michele_laino · Answer

these*

thats not the one im on

michele_laino · Answer

oops.. sorry!!

michele_laino · Answer

are you studying inequalities, right?

Perform the operation indicated, then place the answer in the proper location on the grid. Write your answer in descending powers of a.

By how much does a3 - 2a exceed a2 + a - 6? its fine this is the one im on

michele_laino · Answer

the inequality, which models your exercise, is:
$$\Large {a^3} - 2a > {a^2} + a - 6 + k$$
where $\large  k$ is a real number or another polynomial

michele_laino · Answer

so, I have to compute this difference:

$$\Large {a^3} - 2a - \left( {{a^2} + a - 6} \right)$$
please simplify

countrygirl1431 · Answer

its not inequalties

michele_laino · Answer

yes!  you are right. I meant that my inequality above models your problem.
So, in order to solve your exercise, you have to rewrite that last difference as an ordered polynomial without parentheses
