Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

just a pretty straight forward query I need cleared up.....

If a question asks for the null space of A in cartesian form how do I set it out?

This is what I've got:

X = ( -2; 1; 1)*x3 for all values of x3

Therefore, Null(A) corresponds geometrically to the line through the origin and (-2, 1, 1).

Now do I need to say that this is equivelant to -x = 2y = 2z for it to be in cartesian form or will the above suffice?

thanks for the help
