Here we're going to factor completely 20x squared plus 22x plus 6.
00:06
We will do it using the method of factor by grouping, but it is always important that if there's a gcf, we do want to do that first.
00:14
So it's kind of like an order of operations with factoring.
00:17
Look for a gcf first.
00:19
Here we do have a gcf of 2.
00:22
These are all even.
00:24
Factor out of 2 leaves us with the trinomial 10x squared plus 11x plus 3.
00:32
Now we need to factor this trinomial when factoring it when using grouping.
00:40
The first step is that we do want to replace the 11x.
00:45
The way we're going to do that, we can multiply that a and c value, the 10 and 3.
00:49
That gives us a clue.
00:50
We need factors of 30 that combine to make 11...
