Okay, so we're multiplying together these two binomials.
00:03
We have the quantity negative 2x plus 3 and the quantity xx5 is 4.
00:07
Okay, and we're going to be using the foil method first outer inner last so we're going to be multiplying together the first two terms of the binomials.
00:17
We have negative 2x and x then we're going to multiply together the outer two terms negative 2x and negative 4 then we'll multiply together the inner two terms.
00:26
We have 3 and x and then finally we'll multiply together the last two terms 3 and negative 4.
00:32
Okay, so let's get started.
00:34
First, we're going to multiply negative 2x times x, which is going to give us negative 2x squared.
00:41
Remember to add those exponents together.
00:44
Okay, then we're going to do the outer two terms.
00:46
We have negative 2x and negative 4, which is going to give us positive a x.
00:51
Remember, when we're multiplying together two negative values, we get a positive value.
00:56
Okay, then we multiply the inner two terms...
