Okay, so we are going to expand this binomial x plus y to the fourth power using pascal's triangle.
00:08
Okay, so if this had been to the first power, we would use this row here, the second power, the third power.
00:17
But what we're actually looking for is this row right here.
00:22
Okay, so these values, this one, four, six, four, and one are actually going to be coefficients.
00:27
So we're going to have one, four, six, four, and one.
00:36
Okay, now the x and the y are going to go in for each one.
00:45
And the only thing that's going to differ is the degree.
00:49
Okay, so we started with to the fourth power, so that's where this one is also going to be...
