Here is the right answer:

-4x^2 - 3x - 3 remainder -7

How can this be?

Can you show me step by step why the above answer is correct?

My method may not be like yours, but I can't manage to change it ~~

and x-1.

First, I see the first term of the polynomial -4x^3 and the first term of x-1 : x.
.

So I'll write :


And so on... :






If you want to know where your mistake(s) is/are, just show your work ^^
