$\"20a%5E3-25a%5E2b%2B8ab%5E2-10b%5E3\"$ Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%2820a%5E3-25a%5E2b%29%2B%288ab%5E2-10b%5E3%29\"$ Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"5a%5E2%284%2Aa-5%2Ab%29%2B2b%5E2%284%2Aa-5%2Ab%29\"$ Factor out the GCF of $\"5a%5E2\"$ out of the first group. Factor out the GCF of $\"2b%5E2\"$ out of the second group\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%285a%5E2%2B2b%5E2%29%284%2Aa-5%2Ab%29\"$ Combine like terms\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"20a%5E3-25a%5E2b%2B8ab%5E2-10b%5E3\"$ factors to $\"%285a%5E2%2B2b%5E2%29%284%2Aa-5%2Ab%29\"$ \n" ); document.write( "
