Hey guys,
I'm working on this problem here, and I'm a little fuzzy on how to go about this. I feel like I should put the vectors into a matrix as columns, and row reduce. Here is the question
Consider the vectors u = (3;-7; 2), v = (-1; 1; 3) and w = (-10; 18; 8) in R^3
Prove that w is in the span of u and v, by solving this linear system. When you apply elementary row operations, say explicitly which ones you use.
My problem here is that I'm not sure if matrix row reduction is the right way to go about it, if we are trying to find if a third vector is in the span of only another two in R^3.
The matrix reduces just fine, but I'm not sure if there's more to it. Thanks
