Factorize:
\n" ); document.write( "9a^2 - b^2
\n" ); document.write( "this can be factored as the \"difference of squares\"
\n" ); document.write( "(3a-b)(3a+b)
\n" ); document.write( "and
\n" ); document.write( "3x-8y -4xy + 6
\n" ); document.write( "Group factor here
\n" ); document.write( "3x + 6 - 8y - 4xy
\n" ); document.write( "Factor out 3 and -4y
\n" ); document.write( "3(x+2) - 4y(2+x)
\n" ); document.write( "same as
\n" ); document.write( "3(x+2) - 4y(x+2)
\n" ); document.write( "Factor out (x+2)
\n" ); document.write( "(x + 2)(3 - 4y) \n" ); document.write( "
\n" );
