$\"15y-60\"$ . divide by 15.
\n" ); document.write( "15(y-4) ans\r
\n" ); document.write( "\n" ); document.write( " $\"9Z%5E4%2B27z\"$ . divide by 9z.
\n" ); document.write( "9z(z^3+3) ans.\r
\n" ); document.write( "\n" ); document.write( " $\"-3z%5E5w%5E2-18z%5E3w%5E4\"$ . divide by -3z^3w^2.
\n" ); document.write( "-3z^3w^2(z^2-6w^2) ans.\r
\n" ); document.write( "\n" ); document.write( "( $\"x-5%29%28x%2B7%29=%28x-5%29%28x%2B9%29\"$ . This is an invalid equation.
