Check Perfect Square Trinomial: Determine if the quadratic can be factored using the perfect square trinomial formula.A perfect square trinomial is in the form (a2±2ab+b2)=(a±b)2. We need to check if 4p2−4p+1 fits this pattern.4p2 can be written as (2p)2, and 1 can be written as (1)2. The middle term, −4p, should be equal to 2 times the product of the square roots of the first and last terms if it is a perfect square trinomial.Let's check: 2×(2p)×(1)=4p, but we have −4p, so it fits the pattern with a negative middle term.
Write as Perfect Square Trinomial: Write the expression as a perfect square trinomial.The expression 4p2−4p+1 can be written as (2p)2−2×(2p)×(1)+(1)2.This matches the perfect square trinomial formula (a−b)2=a2−2ab+b2, where a=2p and b=1.
Factor Perfect Square Trinomial: Factor the perfect square trinomial.Using the formula (a−b)2, we can write the factored form of 4p2−4p+1 as (2p−1)2.
