To factor the perfect square trinomials, we will look for expressions of the form \((a + b)^2\) or \((a - b)^2\).

  1. \(x^2 + 6x + 9 = (x + 3)^2\)

  2. \(x^2 + 10x + 25 = (x + 5)^2\)

  3. \(9x^2 + 12x + 4 = (3x + 2)^2\)

  4. \(9x^2 - 30x + 25 = (3x - 5)^2\)

So, the factored forms are:

  1. \((x + 3)^2\)
  2. \((x + 5)^2\)
  3. \((3x + 2)^2\)
  4. \((3x - 5)^2\)
