Check for Perfect Square Trinomial: Determine if the quadratic can be factored as a perfect square trinomial. A perfect square trinomial is in the form (a−b)2=a2−2ab+b2. We need to check if x2−2x+1 fits this pattern.
Identify a and b: Identify the values of a and b that would make x2−2x+1 a perfect square trinomial.For x2−2x+1, a=x and b=1 because (x)2=x2 and (1)2=1. The middle term b0 should be equal to b1, which is b2. This matches the middle term of our expression.
Write Factored Form: Write the factored form using the values of a and b. Since the expression fits the pattern of a perfect square trinomial, we can write it as (a−b)2. Therefore, x2−2x+1=(x−1)2.
