You can put this solution on YOUR website!
Factor:
\n" ); document.write( " $\"x%5E3-125\"$ Do you see this as the difference of two cubes?
\n" ); document.write( " $\"%28x%29%5E3-%285%29%5E3\"$
\n" ); document.write( "The difference of two cubes can be factored thus:
\n" ); document.write( " $\"A%5E3-B%5E3+=+%28A-B%29%28A%5E2%2BAB%2BB%5E2%29\"$ Applying this to your problem, where A = x and b = 5, we get:
\n" ); document.write( " $\"%28x-5%29%28x%5E2%2B5x%2B25%29\"$ \n" ); document.write( "

\n" );
