Linear Algebra Question:

Find the basis of nullspace(A)

A ­= | 4 6 -6 |
| -2 -3 3|
| 0 0 0 |

I hope the formatting looks okay, if not I will fix it shortly. The option to make an equation isn't there right now.

Please help if you can. I don't necessarily need it done for me, only explained :).

Answer 1

Did you notice that the second line is a linear combination of the first?
So the REF would have another line of zeroes leaving the first line.
There are two free variables, so the basis will have two vectors.
Can you take it from here?

Answer 2

yes :) thank you very much

Answer 3

You're welcome!
