My calculations show:
= (-6 + 7t)(-5 + 9t)
= + 30 - 54t - 35t + 63t²
= + 30 - 89t + 63t²

= 30 - 54t - 35t + 63t²
= 63t² - 89t +30
This is the answer obtained from question as given.

Who told you it was 93-89t?
If that answer was in a book, it is a misprint.

Your first answer is the correct one. Someone ignored the t² and added the 63 and 30 to get 93. That is not, repeat, not correct.
