$\"3a%5E3%2B2\"$ = $\"3%28a%5E3%29%2B2\"$ . So if a=1, plug a in and get $\"3%281%5E3%29%2B2\"$ or $\"3%2B2\"$ . so if a=1, then $\"3a%5E3%2B2=5\"$ . Just remember, $\"3a%5E3\"$ is $\"3%28a%5E3%29\"$ and not $\"%283a%29%5E3\"$ . That would be $\"27a%5E3\"$ . So if there are no parentheses, then cube the variable first, and then multiply it by the coefficient. \n" ); document.write( "
