You can put this solution on YOUR website!
Factor: $\"3x+-+12x%5E3\"$ \r
\n" ); document.write( "\n" ); document.write( "First factor 3x:
\n" ); document.write( " $\"3x%281+-+4x%5E2%29\"$ Notice that you now have, in the parentheses, a difference of two squares which can be factored: $\"%28a%5E2+-+b%5E2%29+=+%28a%2Bb%29%28a-B%29\"$ , so:\r
\n" ); document.write( "\n" ); document.write( " $\"3x%281+-+4x%5E2%29+=+3x%281%2B2x%29%281-2x%29\"$ Finally you have:\r
\n" ); document.write( "\n" ); document.write( " $\"3x+-+12x%5E3+=+3x%281+%2B+2x%29%281+-2x%29\"$ \n" ); document.write( "
