OUr expression is:
\n" ); document.write( "

\n" ); document.write( "step 1 - factor each part separately:
\n" ); document.write( "x^2-x = x(x-1)
\n" ); document.write( "x^2 + 3x + 2 = (x+2)(x+1)
\n" ); document.write( "x^2+ 2x = x(x+2)
\n" ); document.write( "x^2-1 = (x+1)(x-1)
\n" ); document.write( "we get
\n" ); document.write( " $\"%28x%2A%28x-1%29%29%2F%28%28x%2B2%29%28x%2B1%29%29\"$ / $\"%28x%2A%28x%2B2%29%29%2F%28%28x%2B1%29%28x-1%29%29\"$
\n" ); document.write( "step 2-Multiply the top fraction by the reciprocal of the bottom fraction to get
\n" ); document.write( " $\"%28x%2A%28x-1%29%29%2F%28%28x%2B2%29%28x%2B1%29%29\"$ * $\"%28%28x%2B1%29%28x-1%29%29%2F%28x%2A%28x%2B2%29%29\"$
\n" ); document.write( "step 3 - cancel where possible to get
\n" ); document.write( " $\"%28x-1%29%5E2+%2F+%28x%2B2%29%5E2\"$ \n" ); document.write( "

\n" );
