Question 924300
<pre>
{{{(4x^4y^2-8x^3y^5+4x^2y^2)}}}{{{"÷"}}}{{{(-4x^2y^2)}}}

{{{(4x^4y^2-8x^3y^5+4x^2y^2)/(-4x^2y^2)}}}

{{{(4x^4y^2)/(-4x^2y^2)-(8x^3y^5)/(-4x^2y^2)+(4x^2y^2)/(-4x^2y^2)}}}

Take care of the signs so that the only signs showing are before each term:

{{{-(4x^4y^2)/(4x^2y^2)+(8x^3y^5)/(4x^2y^2)-(4x^2y^2)/(4x^2y^2)}}}

Cancel and subtract exponents:

{{{-x^2+2xy^3-1}}}
