Check Perfect Square Trinomial: Determine if the quadratic expression 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 9h2+6h+1 fits this pattern.9h2 is a perfect square, as (3h)2=9h2.1 is a perfect square, as 12=1.The middle term, 6h, is twice the product of the square roots of the first and last terms, as 2×3h×1=6h.Thus, the expression is a perfect square trinomial.
Factor Using Formula: Factor the expression using the perfect square trinomial formula.Since we have identified that 9h2+6h+1 is a perfect square trinomial, we can write it as the square of a binomial.(3h)2+2×3h×1+12=(3h+1)2.Therefore, the factored form of 9h2+6h+1 is (3h+1)(3h+1) or (3h+1)2.
