You can put this solution on YOUR website!
Hint: Let $\"z=x%2B3\"$ and use that substitution to get $\"z%5E2-2z%2B35\"$ . Now see if you can factor $\"z%5E2-2z%2B35\"$ . Note: once you're done factoring $\"z%5E2-2z%2B35\"$ , don't forget to plug in $\"z=x%2B3\"$ (to go back to variables in 'x'). \n" ); document.write( "
