Solution

A linear combination of vectors ๐‘ข and ๐‘ฃ is any vector that can be obtained by multiplying each vector by a scalar and then adding (or subtracting) the results. In mathematical terms, any vector ๐‘ค that can be written as ๐‘Ž๐‘ข + ๐‘๐‘ฃ, where ๐‘Ž and ๐‘ are scalars, is a linear combination of ๐‘ข and ๐‘ฃ.

Given ๐‘ข = 0,-2,2 and ๐‘ฃ = 1,3,-1, let's consider a general vector ๐‘Ž๐‘ข + ๐‘๐‘ฃ = (๐‘Ž0 + ๐‘1, ๐‘Ž*(-2) + ๐‘3, ๐‘Ž2 + ๐‘*(-1)) = (๐‘, -2๐‘Ž + 3๐‘, 2๐‘Ž - ๐‘).

So, any vector (๐‘ฅ, ๐‘ฆ, ๐‘ง) that can satisfy this equation for some values of ๐‘Ž and ๐‘ is a linear combination of ๐‘ข and ๐‘ฃ.

For example, if we take ๐‘Ž = 1 and ๐‘ = 2, we get the vector (2, -2 + 6, 2 - 2) = (2, 4, 0), which is a linear combination of ๐‘ข and ๐‘ฃ.

On the other hand, a vector like (1, 1, 1) is not a linear combination of ๐‘ข and ๐‘ฃ, because there are no values of ๐‘Ž and ๐‘ that can satisfy the equation (1, 1, 1) = (๐‘, -2๐‘Ž + 3๐‘, 2๐‘Ž - ๐‘).
