Identify Perfect Square Trinomial: Identify if the quadratic is a perfect square trinomial. 25h2=(5h)2, 4=22, and 20h=2×5h×2. Check if it fits the form (a−b)2=a2−2ab+b2.
Write as Binomial Square: Write the expression as a square of a binomial.(5h)2−2×5h×2+22=(5h−2)2.
Factor Completely: Factor the expression completely.25h2−20h+4=(5h−2)(5h−2) or (5h−2)2.
