You can put this solution on YOUR website!
The area product is simply $\"%283x%2B5%29%28x%2B7%29\"$ , which can multiply if desired to obtain $\"highlight%283x%5E2%2B26x+%2B35%29\"$ .\r

\n" ); document.write( "\n" ); document.write( "You can use Completion of the Square on the trinomial product to put this trinomial into standard form. You would want this form to be like $\"%28x-h%29%5E2%2Bk\"$ .\r
