00:00:00.340 --> 00:00:02.500 A:middle L:90%
the first thing you can do is differentiate the equation
2
00:00:02.500 --> 00:00:06.110 A:middle L:90%
we've been given, which gives us negative to overact
3
00:00:06.110 --> 00:00:11.109 A:middle L:90%
squared minus two acts. Okay, now that we've
4
00:00:11.119 --> 00:00:16.149 A:middle L:90%
got that, we know that when acts is two
5
00:00:17.039 --> 00:00:22.350 A:middle L:90%
, we have 1.55 because we're using the formula Axe
6
00:00:23.089 --> 00:00:29.600 A:middle L:90%
Marchioness to over acts minus X squared plus one divided
7
00:00:29.609 --> 00:00:34.259 A:middle L:90%
by negative to over X squared minus two acts.
8
00:00:34.880 --> 00:00:38.920 A:middle L:90%
Therefore, when X is 1.55 we have acts over
9
00:00:38.920 --> 00:00:42.939 A:middle L:90%
here would be 1.5215
