The condition that "$\displaystyle A(2\vec{v})= \vec{0}$" is peculiar and unnecessary. For A any linear transformation, [math[A(2\vec{v})= 2A(\vec{v}= \vec{0}[/math] if and only if $\displaystyle A(\vec{v})= \vec{0}$ and we were already told that there were non-zero v such that $\displaystyle A(\vec{v})= \vec{0}$.

Also in order that this be true. the vector space must have dimension greater than 1 but I don't believe that is said here.
