Difference of Scalar Multiples of Vectors:
d = 2a - 3b,
where a = 5i -3j + 2k, and b = -4i + j - 3k.
We handle the scalar constant by simply multiplying each component by it:
2a = 10i - 6j + 4k
3b = -12i + 3j - 9k.
Now we take the difference as usual:
d = (10 - (-12))i + (-6 - 3)j + (4 - (-9))k
= 22i - 9j + 13k.
