x^3-22x^2+121x

Explanation:

The way we solve this equation is by using the distributive property. Here is an example of how it works:

In this case, we multiply (11x*11)+(11x*-x)+(-x^2*-11)+(-x^2*-x).
This becomes 121x+(-11x^2)+(-11x^2)+x^3, which we can simplify to 121x-22x^2+x^3.

Standard form is ax^3+bx^2+cx+d, so lets try to rewrite our expression in this form.
It gos from highest degree to lowest, so let's right it like that. x^3-22x^2+121x+0. We can ignore the zero, so we don't need to add it if we don't want to.

The final form is x^3-22x^2+121x
