Learning rigorous proof-writing alone, preparing for exams without teacher feedback, solving advanced Galois theory problems.

:

Find (a') such that (a * a' = 0 \Rightarrow a + a' + aa' = 0 \Rightarrow a'(1+a) = -a \Rightarrow a' = \frac-a1+a). Since (a \neq -1), this is defined. Also (a' \neq -1) (verify). So inverse exists. fundamentals of abstract algebra malik solutions
