First we factor $\"14y%5E2%2B42y%29%29%29+and+%7B%7B%7B7y%5E2%2B35y%2B42\"$
\n" ); document.write( " $\"14y%5E2%2B42y=14y%28y%2B3%29\"$
\n" ); document.write( " $\"7y%5E2%2B35y%2B42=7%28y%5E2%2B5y%2B6%29=7%28y%2B3%29%28y%2B2%29\"$
\n" ); document.write( "Both expressions have $\"7\"$ and $\"y%2B3\"$ as a common factor, so that will help.
\n" ); document.write( " $\"14y%28y%2B3%29%28y%2B2%29=14y%28y%5E2%2B5y%2B6%29=14y%5E3%2B70y%2B84\"$ is the least common multiple, made by multiplying all the factors present in one and/or the other expression. \n" ); document.write( "
