You can put this solution on YOUR website!
Okay, first you need to factor (expand) each polynomial (group: the top of the fraction is a polynomial, and the bottom of the fraction is another polynomial).
\n" ); document.write( "X^2-13x+42 is the same as:
\n" ); document.write( "(x-6)(x-7)
\n" ); document.write( "x^2-36 is the same as:
\n" ); document.write( "(x+6)(x-6)
\n" ); document.write( "You can cross out both (x-6), from the top and the bottom. Here is what is left.
\n" ); document.write( "(x-7)/(x+6)
\n" ); document.write( "That is the simplified form. Hopefully that makes sense, and helps! :) \n" ); document.write( "

\n" );
