00:00:01.000 --> 00:00:02.970 A:middle L:90%
it's clear. So when you're in here So we
2
00:00:02.970 --> 00:00:10.050 A:middle L:90%
have D over D backs. 07 over four.
3
00:00:10.439 --> 00:00:14.349 A:middle L:90%
Next square minus three X plus two. Well,
4
00:00:17.739 --> 00:00:22.030 A:middle L:90%
we have the sum and difference role. So we
5
00:00:22.030 --> 00:00:25.149 A:middle L:90%
have d over DX where we do it separately,
6
00:00:47.590 --> 00:00:53.630 A:middle L:90%
missus. Equal to 7/4 two x to the first
7
00:00:53.630 --> 00:01:00.579 A:middle L:90%
power minus three times one. Next zero power is
8
00:01:00.579 --> 00:01:06.150 A:middle L:90%
equal to seven have that's minus three.
