| 00:30 | . Or 10 X squared Plus the prior to the | |
| 00:36 | outer terms which is two x times positive one Or | |
| 00:41 | positive two x plus . The product of the inner | |
| 00:46 | terms which is negative three times five X . Or | |
| 00:52 | negative 15 X plus the product of the last terms | |
| 00:57 | negative three times positive one which is negative three notice | |
| 01:04 | that positive two X minus 15 X simplifies to negative | |
