### Difficult Problems

1

Solved example of perfect square trinomial

$4x^2-12x+9$
2

The trinomial $is perfect square, because it's discriminant is equal to zero$\Delta=b^2-4ac=-12^2-4\left(4\right)\left(9\right) = 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}$4 Factoring the perfect square trinomial$\left(2x-3\right)^{2}\$
