So given this equation where you have this c plus 1 squared minus 4 times your c plus 1, notice this really is quadratic in form.
00:23
Our variable is the c plus 1.
00:32
If it makes it easier for you, just kind of think of that as 4 times a box and a box squared.
00:41
And we're solving originally, initially for the box.
00:46
So when i think about putting that together.
00:48
So i can factor this because i really have a leading coefficient of one.
00:54
I've got a b of negative 4 and i've got a constant of 3.
00:57
So this is completely factorable.
00:59
Just take it one step at a time.
01:03
So my first factor, remember that my kind of make it look like i put this in the box is the c plus 1.
01:11
That's my variable.
01:17
So to get here, i've got c plus 1 minus 1 as one factor...
