Sum of cubes:
\n" ); document.write( " $\"a%5E3+%2B+b%5E3+=+%28a%2Bb%29%28a%5E2-ab%2Bb%5E2%29\"$
\n" ); document.write( ".
\n" ); document.write( "Factoring numerator:
\n" ); document.write( " $\"3x%5E3%2B24\"$
\n" ); document.write( " $\"3%28x%5E3%2B8%29\"$
\n" ); document.write( " $\"3%28x%5E3%2B2%5E3%29\"$
\n" ); document.write( " $\"3%28x%2B2%29%28x%5E2-2x%2B2%5E2%29\"$
\n" ); document.write( " $\"3%28x%2B2%29%28x%5E2-2x%2B4%29\"$ \r
\n" ); document.write( "\n" ); document.write( "Factoring denominator:
\n" ); document.write( " $\"12-3x%5E2\"$
\n" ); document.write( " $\"3%284-x%5E2%29\"$
\n" ); document.write( " $\"3%282%5E2-x%5E2%29\"$
\n" ); document.write( " $\"3%282-x%29%282%2Bx%29\"$
\n" ); document.write( ".
\n" ); document.write( "So, now we can rewrite:
\n" ); document.write( " $\"%283x%5E3%2B24%29%2F%2812-3x%5E2%29\"$
\n" ); document.write( "as
\n" ); document.write( " $\"%283%28x%2B2%29%28x%5E2-2x%2B4%29%29%2F%283%282-x%29%282%2Bx%29%29\"$
\n" ); document.write( " $\"%28%28x%2B2%29%28x%5E2-2x%2B4%29%29%2F%28%282-x%29%282%2Bx%29%29\"$
