| 00:0-1 | To simplify the negative square root of 24 , we | |
| 00:03 | start by setting up a factor tree 24 is six | |
| 00:09 | times 4 , six is 3 times two and 4 | |
| 00:15 | is two times 2 . Now , since we have | |
| 00:19 | a pair of twos and our factor tree A two | |
| 00:22 | comes out of the radical , however , we also | |
| 00:26 | have a three and a two that do not pair | |
| 00:28 | up , so the three and to stay inside the | |
| 00:31 | radical and we multiply them together to get six . | |
| 00:36 | Finally , don't forget about the negative that's outside the | |
| 00:39 | radical , and we have negative two times the square | |
| 00:43 | root of six . So the negative square root of | |
| 00:45 | 24 simplifies to negative two . Route six . |
