Hello everyone i'm confused on finding the null space on this problem:(adsbygoogle = window.adsbygoogle || []).push({});

the matrix is:

0 2 0 -5

0 1 4 0

0 0 1 0

0 0 0 1

null(A) =

2b - 5d = 0

b + 4c = 0;

c = 0

d = 0;

b = 0;

a = ?

You don't know what a is, so i'm quite confused. Any help?
