1. The problem statement, all variables and given/known data Find two vectors, v1, and v2, whose sum is <-4,1,1>, where v1 is parallel to <2,5,-4>, and where v2 is perpendicular to <2,5,-4> 2. Relevant equations I am guessing I use the cross product for this equation, but I'm confused about how to start this problem. 3. The attempt at a solution any hlep at all would be greatly appreciated!
