Final answer:
The expression x^2 - 2hx + h^2 can be factorized as (x-h)^2.
Step-by-step explanation:
To factorize the expression, we notice that it is in the form of a perfect square trinomial.
A perfect square trinomial can be written as the square of a binomial.
For example, (x-h)^2 is a perfect square trinomial where a = 1, b = -2h, and c = h^2.
Therefore, the factorization of x^2 - 2hx + h^2 is (x-h)^2.
