If m is a solution of x^2=2x-1, show that
i) m^3=3m-2
ii) m^4 - m^2=2m-2.
The question did not ask us to find the value of m. And I do not think the solution would ibe finding the value of m and substituting it back and do the LHS=RHS approach.

i) .
Therefore:
..... (1)
.... (2)
Substitute (2) into (1) and it's blue sky all the way.
ii) Use a similar technique. You might need to use the result found in i).
