If you would like to choose the polynomial written in standard form, you can do this like this:
<span>x^3y^2 + 4x^4y + 10x^9 x^4y^2 + 4x^4y^5 + 10x^2 xy^2 + 4x^3y^8 + 10x^2 x^4y^5 + 4x^3y^2 + 10x^2 </span> Writing the polynomial in standard form means that you have to write<span> the terms by descending degree: </span>x^4y^5 + 4x^3y^2 + 10x^2
The correct result would be <span>x^4y^5 + 4x^3y^2 + 10x^2</span>.
