Factor:
\n" ); document.write( " $\"27-8u%5E3\"$ Rewrite this as:
\n" ); document.write( " $\"-%288u%5E3%2B27%29\"$ Notice that this is the sum of two cubes:
\n" ); document.write( " $\"-%28%282u%29%5E3%2B%283%29%5E3%29\"$ The sum of two cubes can be factored thus:
\n" ); document.write( " $\"A%5E3%2BB%5E3+=++%28A%2BB%29%28A%5E2-AB%2BB%5E2%29\"$ where $\"A+=+2u\"$ and $\"B+=+3\"$ so...
\n" ); document.write( " $\"-%288u%5E3%2B27%29+=+highlight%28-%282u%2B3%29%284u%5E2-6u%2B9%29%29\"$ \n" ); document.write( "
