Determine Factoring Possibility: Determine if the quadratic expression can be factored using the standard form ax2+bx+c. The given expression is already in the standard form, where a=9, b=12, and c=4.
Check Perfect Square Trinomial: Check if the expression is a perfect square trinomial. A perfect square trinomial is in the form (ax)2+2abx+b2, which factors to (ax+b)2. In this case, (3x)2+2(3x)(2)+22=9x2+12x+4, so it is a perfect square trinomial.
Factor Perfect Square Trinomial: Factor the perfect square trinomial.Since 9x2+12x+4 is a perfect square trinomial, it factors to (3x+2)2.
