So we're given two vectors, u, which is equal to negative 1, 2, and v, which is 3, 0.
00:08
And we're going to solve these equations.
00:10
So 2 u, you multiply 2 by each of the components.
00:15
So negative 1 times 2 is negative 2, 2 times 2 is 4.
00:19
Okay.
00:21
And then we found 2u.
00:25
So we're going to put that in here, and we're going to add 3 times v.
00:29
So 3 times 3 is 9, 3 times 0, 0.
00:35
And then we're going to add these components and these components together.
00:41
So negative 2 plus 9 is a positive 7, 4 plus 0 is 4...
