Identify Perfect Square Trinomial: Identify if the quadratic is a perfect square trinomial. 9h2=(3h)2, 4=22, and 12h=2×3h×2. Check if (3h+2)2=9h2+12h+4.
Expand and Verify: Expand (3h+2)2 to verify.(3h+2)(3h+2)=9h2+6h+6h+4=9h2+12h+4.
Factor as Perfect Square: Since the expansion matches the original expression, factor it as a perfect square. 9h2+12h+4=(3h+2)2.
