Okay, hello.
00:01
So here's our expression, 3a squared, c squared, minus 6ac, plus 3.
00:06
We notice we have a common factor of 3 in all three of these terms.
00:09
So if we factor out of 3, then we'd have 3 times, while a squared, c squared, this is back to the first term.
00:17
And then 3 times a, well, a minus 2 ac is a minus 6ac, and then it's just a plus 1.
00:24
It's just back to, well, 3.
00:26
So then can we factor what's inside here? if we factor that further, let's try.
00:32
We have three times...
