Factor\"
\n" ); document.write( " $\"64a%5E3c%5E6%2Bx%5E6y%5E9\"$ Do you recognise this as the sum of two cubes?
\n" ); document.write( " $\"%284ac%5E2%29%5E3%2B%28x%5E2y%5E3%29%5E3\"$
\n" ); document.write( "The sum of two cubes can be factored thus:
\n" ); document.write( " $\"A%5E3%2BB%5E3+=+%28A%2BB%29%28A%5E2-AB%2BB%5E2%29\"$ Applying this to your expression, where: $\"A+=+4ac%5E2\"$ and $\"B+=+x%5E2y%5E3\"$ , we get:
