Check Perfect Square Trinomial: Determine if the quadratic can be factored as a perfect square trinomial.A perfect square trinomial is in the form (a+b)2=a2+2ab+b2. We need to check if 4p2+12p+9 fits this pattern.4p2 can be written as (2p)2, and 9 can be written as 32. The middle term, 12p, should be 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)×3=12p, which matches the middle term.
Write as Perfect Square: Write the quadratic as a perfect square trinomial.Since the quadratic fits the pattern of a perfect square trinomial, we can write it as:(2p+3)2=(2p)2+2⋅(2p)⋅3+32This matches the original expression 4p2+12p+9.
Factor Trinomial: Factor the perfect square trinomial.The factored form of the expression is simply the square of the binomial we identified:(2p+3)2So, the factored form of 4p2+12p+9 is (2p+3)(2p+3) or (2p+3)2.
