25х2-10х+1

To simplify the expression 25x^2 - 10x + 1, we can factorize it if possible or simplify it further.

However, this expression cannot be factorized because it is a quadratic trinomial that does not have any factors.

So, we can leave it as it is:

25x^2 - 10x + 1

This is the simplest form of the expression.
