You can put this solution on YOUR website!
a^2 - a - 20/a^2 - 16 divided by a-5
\n" ); document.write( "-------------
\n" ); document.write( "Factor where you can to get:
\n" ); document.write( "= [(a-5)(a+4)]/[(a-4)(a+4)]/(a-5)
\n" ); document.write( "Invert the denominator and multiply to get:
\n" ); document.write( "= [(a-5)(a+4)]/[(a-4)(a+4)]
\n" ); document.write( "Cancel factors that are common to a numerator and a denominator
\n" ); document.write( "such as (a+4), (a-5)
\n" ); document.write( "= [1/(a-4)]
\n" ); document.write( "===============
