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 (ax)2−2abx+b2, which factors to (ax−b)2. Here, 4x2=(2x)2 and 1=12. The middle term should be −2abx=−2(2x)(1)=−4x. Since the given expression is 4x2−4x+1, it matches the form of a perfect square trinomial.
Factor using Pattern: Factor the expression using the perfect square trinomial pattern.The expression 4x2−4x+1 can be factored as (2x−1)2 because (2x)2−2(2x)(1)+12=4x2−4x+1.
