Okay, here we have this:
Considering the provided polynomial, we are going to rewrite it in standard form, so we obtain the following:
So let's remember that a polynomial is in standard form when its terms are written from highest to lowest degree, so in this case when rearranging we have:
-3x+8x²-11x +9x³
=+9x³+8x²-11x-3x
The previous polynomial corresponds to the given polynomial rewritten in standard form.
