To simplify this expression, first factor out a common factor from each term:
ab - 2b^2 = b(a - 2b)4a^2 = 4a^2a^2 - 4ab + 4b^2 = (a - 2b)(a - 2b)
Now, the expression becomes:(b(a - 2b))/(a - 2b)^2
Since a - 2b cancels out, the final simplified expression is:
b / (a - 2b)
To simplify this expression, first factor out a common factor from each term:

4a^2 = 4a^2
a^2 - 4ab + 4b^2 = (a - 2b)(a - 2b)
Now, the expression becomes:
(b(a - 2b))/(a - 2b)^2
Since a - 2b cancels out, the final simplified expression is:
