(1, a, a^2)
(1, b, b^2)
(1, c, c^2)
I need to do this using column operations, so far I've tried multiplying the 2nd column by abc and subtracting the 3rd column to get the 3rd column, but I can't figure out how to finish off and get the squared letters by themeselves...
Thanks to anyone who takes time to figure this out, it's a big help
