So we want to go ahead and get rid of these parentheses and perform the following multiplication.
00:08
So whenever we have something being multiplied to a polynomial like this, so we have a monomial times a binomial.
00:19
So one term times two terms.
00:22
What we do is we use the distributive property, and that says that whatever is on the outside needs to be multiplied to both terms.
00:33
So what we're going to do is this is going to be equal to we take that 4x, and we first multiply it by the first term.
00:40
So we multiply it by x cubed.
00:43
And then whatever sign is in here goes next.
00:48
And the reason for that is we're taking 4x times negative 7x technically.
00:53
So we have a negative.
00:55
And then we have 4x times 7x.
01:01
So now we just need to perform these multiplications.
01:05
So 4x times x cubed...
