To factor this polynomial, we need to find the factors of 8 that add up to negative 2.
00:06
Factors of 8 are 4 and 2, 8 and 1.
00:11
Not a lot of options.
00:12
So we can cancel that out.
00:15
It's going to be 4 and 2.
00:17
We go ahead and fill out our binomials, and we can put a b, a b, a 4, and a 2.
00:25
It does not matter the order.
00:27
What matters is the signs.
00:28
So now to figure out what signs go here and here, we look.
00:32
Look at this sign first...
