"WebWe should be checking that v1+v2 is in the nullspace. What it means to be in the nullspace is that A (v1+v2) should be the zero vector. But A (v1+v2)=Av1+Av2 (because matrix transformations are linear). Now if we assumed v1 and v2 are in the nullspace, we would have Av1=0 and Av2=0. So A (v1+v2)=Av1+Av2=0+0=0.
