55. 45m^2n^3-36mn^2+63m^3n
\n" ); document.write( "Common factor is 9mn.
\n" ); document.write( "=9mn(5mn^2-4n+7m^2)
\n" ); document.write( "----------------\r
\n" ); document.write( "\n" ); document.write( "57. 3a(1-5b)-4b(1-5b)
\n" ); document.write( "Common factor is 1-5b
\n" ); document.write( "=(1-5b)(3a-4b)
