Answer 2

Answer:

x^2 - 2 x - 9

Step-by-step explanation:

Given what should be subtracted from X square +3 x cube +4 x square -3 x -6 to get 3 x cube +4 x square -x + 3​

So a small example of subtraction.

We can write as

What should be subtracted from 10 chocolates to get 5 chocolates?

So it will be 10 - 5 = 5

In the same way we can do it as

x ^2 + 3 x^3 + 4 x^2 - 3 x - 6

          3 x^3 + 4 x^2 - x   + 3

------------------------------------------- sign changes while subtracting.

x^2 - 2 x - 9

So x^2 - 2 x - 9 should be subtracted  from x square +3 x cube +4 x square -3 x -6 to get 3 x cube +4 x square -x + 3​
