We're being asked to multiply the given expressions.
00:03
To do this, we're going to use the distributed property.
00:05
So we're going to take the first term in our first set of parentheses, x to the n power, and multiply it by our second set of parentheses, x to the n plus 3.
00:15
Then we're going to take the second term in that first preemphasy, which is negative 1, and also multiply it by the second preemphasy, x to the n plus 3.
00:23
And now we just distribute.
00:25
So we have to multiply x to the n times x to the n.
00:28
Well, remember, when you multiply like basis, is you just add the exponents.
00:32
So n plus n would be 2n.
00:34
So we'll have x to the 2n power...
