### Difficult Problems

1

Solved example of perfect square trinomial

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

The trinomial $4x^2-12x+9$ is a perfect square trinomial, because it's discriminant is equal to zero

$\Delta=b^2-4ac=-12^2-4\left(4\right)\left(9\right) = 0$
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
