simplify m+2/m-2 divided by 2m+4/m^2-4
\n" ); document.write( "-----
\n" ); document.write( "[(m+2)/(m-2)] / [(2m+4)/(m^2-4)]
\n" ); document.write( "-----
\n" ); document.write( "Factor:
\n" ); document.write( "[(m+2)/(m-2)] / [(2(m+2))/(m-2)(m+2))]
\n" ); document.write( "-----
\n" ); document.write( "Invert the denominator and multiply:
\n" ); document.write( "[(m+2)/(m-2)] * [(m+2)(m-2)/(2(m+2))
\n" ); document.write( "----
\n" ); document.write( "Cancel any factor common to numerator and denominator to get:
\n" ); document.write( "----
\n" ); document.write( "[(m+2)/1] * [1/(2)
\n" ); document.write( "--------------
\n" ); document.write( "= (m=2)/2
\n" ); document.write( "============\r
\n" ); document.write( "\n" ); document.write( "also [x-1/2x+1 divided by 1-x/2x+1]
\n" ); document.write( "----
\n" ); document.write( "Invert the denominator and multiply:
\n" ); document.write( "----
\n" ); document.write( "= [x-1/2x+1 times 2x+1/1-x]
\n" ); document.write( "------
\n" ); document.write( "= [-1/1 times 1/1]
\n" ); document.write( "---
\n" ); document.write( "= -1
