It would help if you could see this binomial as the sum of two cubes?
\n" ); document.write( " $\"64x%5E3%2B343+=+%284x%29%5E3%2B%287%29%5E3\"$
\n" ); document.write( "The sum of two cubes can be factored thus:
\n" ); document.write( " $\"A%5E3%2BB%5E3+=+%28A%2BB%29%28A%5E2-AB%2BB%5E2%29\"$
\n" ); document.write( "So, with A = (4x) and B = 7, you get:
\n" ); document.write( " $\"64x%5E3%2B343+=+highlight%28%284x%2B7%29%2816x%5E2-28x%2B49%29%29\"$
\n" ); document.write( " \n" ); document.write( "
