Factor x^2-2xy+y^2

Problem

x2−2*x*y+y2

Solution

1. Identify the structure of the expression as a trinomial of the form a2−2*a*b+b2

2. Recognize the pattern for a perfect square trinomial, which follows the identity (a−b)2=a2−2*a*b+b2

3. Assign the variables from the expression to the identity, where a=x and b=y

4. Rewrite the expression in its factored form as the square of a binomial.

Final Answer

x2−2*x*y+y2=(x−y)2
