Find u - 2v given that u =(-2,5) and v = 6i -4j

Answer 1

To find u - 2v, first we need to find the value of 2v and then subtract it from u.

Given that u = (-2, 5) and v = 6i - 4j, we can write 2v as:

2v = 2(6i - 4j)
2v = 12i - 8j

Now, let's find u - 2v:

u - 2v = (-2, 5) - (12i, -8j)
u - 2v = (-2 - 12i, 5 + 8j)
u - 2v = (-2 - 12i, 5 + 8j)

Therefore, u - 2v = (-2 - 12i, 5 + 8j)
