WebSolved Problems Difficult Problems 1 x x The trinomial 4x2 −12x+9 is a perfect square trinomial, because it's discriminant is equal to zero \Delta=b^2-4ac=-12^2-4\left (4\right)\left (9\right) = 0 Δ = 0 3 Using the perfect square trinomial formula a^2+2ab+b^2= (a+b)^2,\:where\:a=\sqrt {4x^2}\:and\:b=\sqrt {9} a2 +2 b2 = (a b 4 WebAdding 9 9 to x^2+6x x2 +6x in row \blueD { (2)} (2) had the fortunate result of making the expression a perfect square that can be factored as (x+3)^2 (x +3)2. This allowed us to solve the equation by taking the square root. This was no coincidence, of course.
