You can put this solution on YOUR website!
1) Realize that you have a difference of squares in $\"16x%5E2-p%5E2\"$ ;
\n" ); document.write( "use the special product $\"a%5E2-b%5E2=%28a-b%29%28a%2Bb%29\"$ ,
\n" ); document.write( "and then take out the common factor $\"%284x-p%29\"$ :
\n" ); document.write( " $\"16x%5E2-p%5E2%2B4x-p=%284x-p%29%284x%2Bp%29%2B%284x-p%29=%284x-p%29%284x%2Bp%2B1%29\"$
\n" ); document.write( "
\n" ); document.write( "2)

\n" ); document.write( "
