1. The problem statement, all variables and given/known data Show that the set of functions: x^2 3x+2 x-1 2x+5 are linearly dependent. 2. Relevant equations - 3. The attempt at a solution I know that you have to show that you can put constants in front of each equation (that aren't all zero) such that: c1y1 + c2y2 + c3y3 + c4y4 = 0 i.e. c1(x^2) + c2(3x+2) + c3(x-1) + c4(2x-5) =0 But I have no idea how to do this?
