[x^3-x^2-10x/x^2-8x+16] + [-3x^2-6x+64/x^2-8x+16]\r
\n" ); document.write( "\n" ); document.write( "The denominators are the same so combine the numerators:\r
\n" ); document.write( "\n" ); document.write( "= [ x^3-4x^2-16x+64]/[(x-4)^2]\r
\n" ); document.write( "\n" ); document.write( "= [x^2(x-4)-16(x-4)]/[(x-4)^2]\r
\n" ); document.write( "\n" ); document.write( "= [(x-4)(x^2-16)]/[(x-4)^2\r
\n" ); document.write( "\n" ); document.write( "= [ (x-4)^2(x+4)]/[(x-4)^2]
\n" ); document.write( "Cancel the (x-5)^2 factors to get:\r
\n" ); document.write( "\n" ); document.write( "= x+4
