I´m taking linear algebra, and the professor asked us to get back next class with many methods to solve this exercise. I can´t find even one after 2 hours of thinking, really sad. Could you please help?
I´ve the following matrix "A", which represent a linear transformation:
a 0 -2a 0 2a -3a 0 -2a -a 0 3a 0 0 a -a 2a
and I need to find what the title says.
Thanks for your help!!!
