Simplify an expression in symbolic matrix

I have the following vector: (-(q + 1/q)*q^2 + q^3 + q, 0, 0, 0, 0, 0, 0, 0) Which command should I use to make the above vector simplify to (0, 0, 0, 0, 0, 0, 0, 0) I tried .simplify_full and .simplify_rational, but it didn't work.

First off, .simplify_full() does work for me - like in this example:

q = var('q')
v = vector( (-(q + 1/q)*q^2 + q^3 + q, 0, 0, 0, 0, 0, 0, 0) )
print( v.simplify_full() )

Alternatively, you can explicitly apply .simplify_full() to each element:

print( v.apply_map(lambda t: t.full_simplify()) )
