So this question once again wants us to factor out the expression that we have here, which is 3x squared minus 16x plus 5.
00:07
And so to do this, as it states in the book, we just need to use guess and check to figure out what the factor is.
00:16
So let me write out this here.
00:21
So we know these first terms are going to have an x in them.
00:25
We don't know what the coefficient is.
00:26
But we also know that the coefficients of these x terms need to multiply together to equal three.
00:34
And so we know for a fact that these two have to be three and one, because those are the only factors of three.
00:46
Now, these terms here at the end need to multiply together to equal five, but there's also this negative term here.
01:00
So it's likely that both these terms are going to be subtracted off from each other...
