The result of simplification is (root number 3- root number 2). Step: 3 times the root number 2 in the molecule and write the root number 2 plus 2 times the root number 2. The molecule can be (1 plus root number 2 minus 2) multiplied by (root number 3- root number 2), and (root number 3- root number 2) can be written as 2/ (root number 3+ root number 2).
